专利说明:

The invention relates to a reversal system for a telescopic sight, wherein the reversing system has at least two lenses mounted in at least one tube of the reversing system parallel to an optical axis of the reversing system and relatively displaceable relative to each other, wherein by a displacement of the at least two displaceably mounted lenses, a magnification, with an image designed in a first image plane of the inversion system is imaged into a second image plane of the inversion system, wherein the at least two displaceable lenses are arranged in all positions between the first and the second image plane.
In addition, the invention relates to a telescopic sight with a lens and an eyepiece and arranged between the lens and the eyepiece center tube, wherein in the center tube, a reversing system is arranged, wherein the first image plane of the reversing system facing the lens and the second image plane of the reversing system to the eyepiece in which an intermediate image designed by the objective in the first image plane is imaged by the inversion system in the second image plane.
Image magnification in the present context means the ratio of the size of an image of an object in the second image plane of the inverse system divided by the size of the image of the object in the first image plane of the inverse system.
By way of introduction, it should be noted that in this document the term lenses means both single lenses and lenses composed of several individual lenses (cemented lenses). Such composite te lenses can be made for example by gluing or cementing two or more individual lenses together.
An inversion system and a telescopic sight of the aforementioned type have become known from EP 1 746 451 B1. In the known inversion system, the magnification of the inverse system, i. the magnification with which an image designed in the first image plane of the reversal system is imaged into the second image plane is changed by moving the lenses. By increasing the travel of the lenses, the zoom range of the known inverse system could be increased (i.e., the ratio of absolute maximum magnification to absolute minimum magnification). However, the increase of the displacement path is accompanied by an extension of the inversion system and thus of the tube of the inversion system.
Due to this structural change in the realization of a reversal system with a large zoom and a large range of displacement of the lenses, especially at the higher magnification positions, there may be an enlargement of the exposed part of the inside of the tube of the reversing system, to which disturbing reflections of ambient light incident on the inverting system that is not parallel to the optical axis will occur. The reflections have a particularly disturbing effect if the displaceable lenses of the reversing system are in a position which corresponds to the greatest magnification of the reversing system.
It is therefore an object of the invention to provide a solution which, with a large range of change of the magnification of a reversal system, enables a good suppression of interfering light reflections, in particular at higher values of the magnification positions.
This object is achieved with a reversing system of the aforementioned type according to the invention in that one of the optical axis facing surface of the inside of a tube at least one absorption area with absorption zones for absorbing incident light and with lying between adjacent absorption zones sliding surfaces for carriers, the at least two slidably mounted lenses, wherein an area sum of the sliding surfaces is smaller than an area sum of the absorption zones, wherein the at least one sliding surface is arranged at a different distance to the optical axis than the at least one absorption zone.
The absorption zone can be realized by an absorption-increasing coating, for example a high-absorbency lacquer or by applying absorbent surface structures or by machining the surface. The sliding surface, however, can be made, for example, by smoothing the surface. The solution according to the invention enables a very efficient suppression of reflections of the reversing system.
In order to ensure a good displaceability of the displaceable lenses of the reversing system in the tube while suppressing reflections, it can be provided that a ratio of the at least one absorption zone to at least one sliding surface is greater than or equal to 2: 1.
A particularly efficient suppression of reflections can be achieved in that the at least one absorption zone has a distance of more than 30 μm, in particular 40 μm, from the optical axis or greater than the at least one sliding surface.
A further development of the invention, according to which sliding surfaces 27 and absorption zones 26 are arranged alternately successively in a longitudinal section of inner side 20 of reversing system tube 12 parallel to optical axis 14, is advantageous inasmuch as such an embodiment of the absorption region acts on longitudinally and slantingly incident light especially effective.
According to a preferred variant of the invention it can be provided that the at least one absorption zone has at least one obliquely or transversely to the optical axis groove, said at least one groove in the optical axis facing surface of the tube by removing a wall of the tube forming Material is formed, wherein the sliding surfaces is formed from at least one web, which is formed from not abraded material of the wall of the tube.
Optimal displaceability of the displaceable lenses along the tube without adversely affecting the reflection suppression can be achieved by the fact that the at least one web has a width whose magnitude comes from one of the value ranges lying between 0.05 mm and 0.5 mm.
According to an advantageous variant of the invention, which is characterized by a further improvement of the reflection suppression, it can be provided that the at least one groove has a depth whose amount comes from one of the lying between 0.05 mm and 1 mm range of values.
In addition, the at least one groove may each have a width at their widest point, the amount of which originates from a value range lying between 0.2 mm and 0.3 mm.
According to a preferred variant of the invention, it can be provided that the at least one groove is formed by a helically or threadwise on the inner surface of the tube facing the optical axis and around the optical axis circumferential recess in a wall of the tube
Advantageously, the at least one helically encircling groove has a pitch whose magnitude comes from a value range lying between 0.2 mm and 2 mm.
A particularly good suppression of false light can be achieved in that an angular symmetry of an opening angle of the at least one groove are inclined in the direction of the first image plane of the reversing system.
The suppression of disturbing reflections in a grazing incidence of light can be improved by the fact that the at least one groove has a leading edge in the direction of the first image plane and in the at least one web and a trailing edge extending obliquely to the leading edge, wherein the leading edge and the trailing edge a Include acute angles with each other and includes the leading edge or a tangent to the leading edge at an angle with the optical axis having an amount that comes from a lying between 20 ° and 24 ° range of values. It has proved to be particularly favorable in this case if a transition region between the trailing edge and the leading edge has a radius of curvature which is smaller than 0.05 mm.
As an alternative to the use of a helical groove, however, provision may also be made for the at least one absorption zone to have a plurality of grooves arranged one behind the other, viewed in the direction of the optical axis, in particular as grooves formed annularly around the optical axis and closed in grooves.
The tube preferably has a length whose amount comes from a range of values which is between 80 mm and 150 mm. This is particularly advantageous in terms of achieving a large adjustment range in which the magnification of the inverse system can be changed.
In order to enable installation of the reversal system in riflescopes with central tubes of conventional thickness, it may be provided that the tube whose surface facing the optical axis has the grooves has an outer diameter which is smaller than 35 mm.
Preferably, in a position of the at least two movable lenses, which corresponds to a maximum magnification of the inversion system, an amount of a value of the magnification between the first and second image plane of the inversion system, at least 7, in particular at least 8 (in terms of the absolute amount of the image scale, ie without Consideration of the sign of the image size).
Furthermore, it can be provided that in a position which corresponds to at least two movable lenses, which corresponds to a smallest magnification of the inversion system, an amount of a value of the magnification, between the first and second image plane of the inversion system, is at least 0.9, in particular at least 1 ( also in the sense of the absolute amount of the image scale).
Furthermore, in the position of the at least two movable lenses, which corresponds to the smallest magnification of the inversion system, the amount of the value of the magnification, between the first and second image plane of the inversion system, can be at most 1.2.
To be particularly favorable in terms of the suppression of reflections on the inside of the tube, it has been found that the at least one absorption zone is arranged at least in a region which is in a position of at least two displaceably mounted lenses, which corresponds to the largest magnification, with the the image designed in the first image plane of the inversion system is erected and enlarged in the second image plane of the inversion system, viewed from the direction of the at least two displaceably mounted lenses behind which at least two movably mounted lenses are located.
In order to improve the displaceability of the lenses displaceably mounted in the tube, it can be provided that the surface of the inside of the at least tube which faces the optical axis is coated at least in sections with a friction-minimizing layer.
In addition, the surface of the inside of the at least one tube which faces the optical axis can be smoothed, in particular by polishing, honing, grinding or by means of a chip-removing method.
According to a preferred embodiment of the invention, each of the carriers of the at least two displaceably mounted lenses is designed substantially as a tubular sleeve, wherein on a shell outer surface of each of the carrier at least three webs are arranged, through which the respective carrier on the surface facing the optical axis the inside of the at least one tube is supported. In addition, it can be provided that the at least one tube, in which the two carriers of the lenses are mounted axially displaceable, has at least one longitudinal groove extending parallel to the optical axis and is arranged in a rotatably mounted about the optical axis control tube, wherein the head tube at least two curved control grooves and at least one of both in the longitudinal groove and in one of the at least two control grooves engaging driving pin is arranged, wherein the driving pins of different carrier engage in different control grooves, wherein at least one fitting on the lateral surface of the control tube and the Jacket surface annularly comprehensive reinforcing ring is arranged. By rotating the control tube, the carriers of the lenses can be displaced in the longitudinal direction of the tube and thus the magnification of the reversal system can be changed. By the reinforcing ring, the mechanical stability of the control tube and thus the entire reversing system is substantially increased. The embodiment of the invention described in this paragraph can also be realized without the presence of the absorption zones described above and form the subject of a separate invention, which solves the task of increasing the mechanical stability of a relevant inversion system, by the arrangement of the reinforcing ring.
In addition, the position of the first image plane and the position of the second image plane of the inversion system can be constant regardless of the current position of the at least two displaceably mounted lenses in the direction of the optical axis.
The abovementioned object can also be achieved with a sighting telescope of the type mentioned in the introduction by having a reversing system according to one of claims 1 to 22.
Preferably, the lens of the rifle scope according to the invention has a focal length, the amount of which comes from a range of values which is between 45 mm and 49 mm.
The eyepiece of the riflescope according to the invention, for example, have a focal length whose amount is in a range between 45 mm and 49 mm.
In addition, the scope can have an exit pupil, which is smaller than 4 mm, in particular smaller than 3.5 mm.
According to a preferred variant of the invention, it is provided that, at the smallest magnification, with which an intermediate image designed in the first image plane of the reversal system is imaged into the second image plane of the reversal system, the telescopic sight has an overall magnification whose magnitude comes from a range of values is between 0.7 and 10, wherein the total magnification of the scope at the largest magnification, with which an intermediate image designed in the first image plane of the inversion system is imaged into the second image plane of the inversion system, has an amount that originates from a value range between 6 and 80 is.
Furthermore, the center tube of the riflescope may have an outer diameter which is less than or equal to 35 mm.
For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. All statements of value ranges in the present description should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all sub-areas begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
Fig. 1 shows a side view of a telescope 1 with adjustable magnification. According to this embodiment, the telescope 1 is formed by a telescopic sight. In this case, in addition to a lens 2 and an eyepiece 3 in a central tube 4 of the telescope 1, a lens comprehensive reversing system 5 (Fig. 2) is arranged.
FIG. 2 shows a detail of the riflescope 1 according to FIG. 1 with a center tube 4 shown in section. The reversing system 5 is pivotally mounted in the interior of the central tube 4 in a manner known per se, thereby enabling adjustment of a crosshair in so-called shooting together with a weapon , This adjustment or pivoting of the reversing system 5 in the
Central tube 4 of the telescope 1 takes place in a likewise known manner with the aid of a height tower 6 (FIG. 1) and a side tower. To change or to adjust the magnification of the telescope 1, this has at the eyepiece end in front of an eyepiece housing 7 a collar 8 for the zoom setting. The adjusting ring 8 is rotationally coupled to a control tube 9 of the reversing system 5. Control grooves 10, 11 which are formed in the control tube 9, allow for rotation of the control tube 9 on a reversing system tube 12, an adjustment axially displaceable lenses of the reversing system 5 (Fig. 3).
FIG. 3 shows a longitudinal section of the reversing system 5 according to FIG. 2. The optical elements of this reversal system 5 cause an inversion or elevation of an image generated in an objective-side intermediate image plane 61 of the telescopic sight 1 into an eyepiece-side intermediate image plane 62 of the telescopic sight 1. the optical elements of the inversion system 5 but also a variability of the image scale between the first lens-side image plane 61 and the second eyepiece-side image plane 62 and thus a corresponding or proportional change of the total magnification of the telescope 1 between a minimum total magnification and a maximum total magnification. The optical elements of the reversing system 5 thus simultaneously form a so-called zoom system.
As these optical elements, the optical system of the inversion system 5 first includes a field lens 13 disposed in an objective-side end portion of the inversion system 5. Towards an eyepiece-side end region, along an optical axis 14, a first zoom lens 15, a second zoom lens 16 and a diverging lens 17 follow. The two zoom lenses 15, 16 are each held in a support 18, 19 and common slidable along the optical axis 14. For this purpose, the two carriers 18, 19 are mounted on an inner side 20 of the reversing system tube 12 and slidably mounted in the direction of the optical axis 14.
The carriers 18, 19 each have a driving pin 21, 22 projecting in the axial direction (with respect to the optical axis 14). These driver pins 21, 22 extend through a longitudinal groove 23 formed in the reversing system tube 12 and into one of the two control grooves 10, 11 of the control tube 9. In this way, between the reversing system tube 12, the control tube 9 and the two carriers 18, 19 with the zoom lenses 15, 16, a cam mechanism is formed, through which the zoom lenses 15, 16 can be moved in the axial direction. For this purpose, the curve shapes of the cam grooves 10,11 are formed in the control tube 9 such that upon displacement of the zoom lenses 15, 16, the position of the two intermediate image planes 61,62 not changed (at least for the limiting case of a picture of an infinite located object ).
In the illustrated embodiment, an adjustment range in the axial direction with a length 81 of about 55 mm is determined by the control groove 10 for the carrier 18 and zoom lens 15. The cam groove 11 allows for the zoom lens 16 and the second carrier 19, respectively, a range of movement of a length 82 of about 61 mm, with a length 83 of the inverting system tube 12 having a diameter of 115.2 mm. In alternate embodiments of the inversion system 5, the length 83 of the inverting system tube 12 may assume values in the range of 80 mm to 150 mm.
The lenses of the inversion system 5 have the following focal lengths, each related to a wavelength of the light of 546 nm. The field lens 13 has a focal length of +54.1 mm; the first zoom lens 15 has a focal length of +37.8 mm; the second zoom lens 16 has a focal length of +41.6 mm and the diverging lens 17 a (negative) focal length of -29.6 mm. The arrangement of the lenses relative to each other is chosen so that a distance 63 between the first image plane 61 and the field lens 13 has a value of 11.3 mm and a distance 64 between the diverging lens 17 and the second image plane 62 has a value of 30.8 mm wherein an image plane distance 65 of the second image plane 62 from the first image plane 61 has a value of 137 mm.
In alternative embodiments of the inversion system 5, the values of the focal lengths may be in the following ranges. The focal length of the field lens 13 between 44.1 mm and 64.1 mm; the focal length of the first zoom lens 15 is between 27.8 mm and 47.8 mm; the focal length of the second zoom lens 16 is between 31.6 mm and 51.6 mm; and the focal length of the diverging lens 17 is between -39.6 mm and -19.6 mm. Accordingly, the values of the lengths and distances given above can be varied by +/- 20%.
In accordance with the preferred embodiment of the invention, by adjusting the zoom lenses 15, 16 along the optical axis 14, a magnification in a value range of -1.038 (in the smallest overall magnification of the telescope 1) to -8.238 (in the largest overall magnification of the telescope 1) lie and thus a zoom factor reach a value of 8.
Such high values of the zoom factor (compared to the usual values of up to 4 or 6) make a high accuracy of fit of the guide of the carrier 18, 19 in the inverting system tube 12, as well as a high precision in the displacement of the carrier 18, 19 in the axial direction by the interaction of the driving pins 21,22 with the cam grooves 10, 11 and the longitudinal groove 23 is required. In the reversing system 5, therefore, a reinforcing ring 24 is additionally provided, which is arranged adjacent to the circumference of the control tube 9 or attached.
As shown in Fig. 3, a corrugation of the surface is provided in a region 25 and in a longitudinal region of the surface of the inner side 20 of the inversion system raw rs 12.
FIG. 4 shows a detail from the area 25 of the reversing system tube 12 with the support 18 according to FIG. 3, greatly enlarged. The carrier 18 abuts against the inner side 20 of the inverting system tube 12 and, in such a way, can be slid on the inner side 20 in the longitudinal direction of the reversing system 5. As shown in Fig. 4, the carrier 18 is located in the corrugated region 25 of the inside 20 of the inverting system tube 12 (Fig. 3). Accordingly, 12 grooves 26 are formed in the inside 20 of the inverting system tube. These grooves or grooves 26 contribute to the fact that on the inner side 20 of the reversing system tube 12, the incident light does not lead to the object to be viewed disturbing stray light.
To avoid stray light, it is generally intended to blacken (e.g., black anodize) the interior walls of lens frames and optical housings. It turns out, however, that especially with very smooth surfaces and very flat or abrasive angles of incidence of the light rays, a blackening of the surface alone is not sufficient. Incidentally, if in this description of "scattered light" is mentioned, the standardized measurement according to DIN ISO 14490-6 (optics and photonics, test method for telescopes, Part 6: Determination of the proportion of stray light) reference.
In order to suppress stray light, it may be provided to form the region 25 of the inner side 20 of the inverting system tube 12 with a successively successive sequence of grooves or grooves 26. As shown in FIG. 4, the grooves 26 are formed by toroidal recesses in the inner side 20 of the inverter tube 12. The cross section of the groove 26 is triangular in this case.
According to an alternative embodiment, the grooves 26 are formed by a helical or thread-like depression. The grooves or grooves 26 in the region 25 of the inner side 20 can thus also extend transversely or obliquely with respect to the optical axis 14 of the reversing system 5.
Each of the grooves 26 forms an absorption zone for light rays incident thereon. The preparation of these grooves 26 is preferably carried out by removing a material forming a wall of the inverting system tube 12, for example by milling or turning. Thereby, a sequence of the grooves 26 forming recesses or grooves and between adjacent grooves 26 lying sliding surfaces 27 is generated. According to this embodiment, the grooves 26 are made with a width 28 having a value of 0.25 mm and a depth 29 having a value of 0.1 mm. A width 30 of the sliding surfaces 27 between two adjacent grooves 26 has a value of 0.1 mm. A ratio of the width 28 of a groove 26 to the width 30 of a sliding surface 27 is preferably greater than 1: 1. Favorable for the light-absorbing effect is, inter alia, when the surface portion of the groove 26 and the absorption zones is correspondingly high. A choice of the width 28 of the grooves 26 and the width 30 of the sliding surfaces 27 is advantageously such that an area of the groove 26 to an area of the sliding surface 27 in a ratio of equal to or greater than 2: 1 stands.
In this case, the value of the surface of the groove 26 that is projected perpendicular to the inside 20 of the reversing system tube 12 should be understood as the area of the groove 26 or the absorption zone. Accordingly, the conditions mentioned are to be understood and these relate to the absorption region or the region 25 of the inner side 20 of the reversing system tube 12. It is advantageous if in the region 25, an area total of the sliding surfaces 27 is smaller than an area total of Absorption zones 26.
The absorption zones predominantly have a distance or radius with respect to the optical axis 14 that is greater by 30 μm than the sliding zone 27.
It proves to be particularly advantageous if, in a longitudinal section of the inner side 20 of the reversing system tube 12 parallel to the optical axis 14, sliding surfaces 27 and absorption zones 26 are arranged alternately successively. Namely, the reflection-suppressing effect of the absorption region on the inner side 20 of the inverter tube 12 is particularly effective in the longitudinal and abrasive light.
Fig. 5 shows a detail of the inside 20 of the inverting system tube 12 having an alternative cross-sectional shape of the groove 26. The groove 26 or absorption zone has a substantially triangular cross-sectional shape defined by a leading edge 31, a trailing edge 32 and the imaginary extension the inside 20 of the inverting system tube 12 is limited. The leading edge 31 and trailing edge 32 preferably include an angle 33 that forms an acute angle. On the other hand, the leading edge 31 includes an angle with the optical axis 14 (Fig. 3) whose value is in a range between 20 ° and 24 °. The leading edge 31 is the boundary surface of the groove 26 which is closer to the lens-side end of the reversing system 5 (FIG. 3), whereas the trailing edge 32 is the boundary of the groove 26 which is closer to the eyepiece-side end region of the reversing system 5. The formation of the groove 26 is also designed such that an angular symmetry 34 of the angle 33 enclosed by the front flank 31 and the trailing flank 32 is inclined in the direction of the lens-side end region or in the direction of the first image plane 61 of the reversing system 5. The leading edge 31 and the trailing edge 32 of the absorption zone and the groove 26 to a certain extent form a V-shape, the opening of which is directed against the incident of the obektivseitige end portion of the reversing system 5 light. Incidentally, the groove 26 is made by machining methods such as milling or turning such that a transition area between the leading edge 31 and the trailing edge 32 has a radius of curvature 35 which is smaller than 0.05 mm. In particular, it is advantageous for avoiding the generation of stray light when the trailing edge 32 encloses an angle with the optical axis 14 (FIG. 3) which is greater than 70 °. So is an angle of 90 ° as in the embodiment of FIG. 4, but there are also angles greater than 90 °, possible. At an angle between the trailing edge 32 and the optical axis 14 of more than 90 °, there is finally an undercut of the sliding surface 27, as shown in the embodiment of FIG.
FIG. 7 shows a further exemplary embodiment of the corrugation in the area 25 of the inner side 20 of the reversing system tube 12 according to FIG. 3. The cross-sectional shape of the grooves 26 in this embodiment is rectangular, that is to say both the leading edge 31 and the trailing edge 32 close the optical axis 14 a right angle. For the formation of the corrugation in the region 25 of the inner side 20 of the reversing system tube 12, in particular the following dimensions or value ranges have been found to be favorable. The width 30 of the sliding surfaces 27 or the webs between adjacent grooves 26 is preferably selected from a value range between 0.05 mm and 0.5 mm. The depth 29 of the grooves 26 may have values in a range between 0.05 mm and 1 mm. The width 28 of the grooves 26 may have values in a range between 0.2 mm and 0.3 mm. In one embodiment of the grooves 26 by a thread-like or helical circumferential depression, the value of the pitch or the value of the pitch of a range between 0.2 mm and 2 mm can be selected.
In the manufacture of the inverting system tube 12, that is to say in particular during the production of the inner side 20 and the grooved portion 25 of the reversing system tube 12, it is provided that in a final treatment step the webs or sliding surfaces 27 are worked by honing to ensure a precise as possible seat of the carrier 18, 19 with the two zoom lenses 15, 16.
Fig. 8 shows representative of the two carriers 18, 19, the carrier 18 shown in perspective. This has a substantially cylindrical outer shape and has at its periphery or on a jacket 36 with respect to the optical axis 14 radially projecting driver pin 21. The jacket 36 of the carrier 18 deviates from an ideal enveloping cylinder jacket insofar as parallel to the optical axis 14 extending sliding webs 37 are formed, lying between two sliding webs 37 areas of the shell 36 has a smaller radius with respect to the optical axis 14 than the radius the sliding webs 37 is. The carrier 18 has at least three or more than three such sliding ribs 37, which are preferably distributed equidistantly over the circumference of the shell 36 of the carrier 18. In the illustrated embodiment, the jacket 36 of the carrier 18 on six sliding webs 37. When installed, the carriers 18, 19 in the reversing system tube 12 are thus only in contact with the inside 20 and the sliding surfaces 27 of the reversing system tube 12 by means of their sliding webs 37.
Incidentally, with the reversing system 5 according to the invention, riflescopes 1 with a subjective field of view with a value greater than 23.0 °, preferably with a value from a range of 23.5 ° to 24.5 °, can be produced. For this purpose, the reversing system 5 is combined, for example, with an eyepiece 3 with a value of the focal length of 47.9 mm. A value of the focal length of the lens is, for example, 46.2 mm.
