    专利说明:

    The invention relates to an optical device for displaying a line image or a target mark in a measuring or riflescope, comprising - a reticle having a line image arranged on a surface, - a light source for illuminating this line image - wherein the reticule has a laterally to the line image Surface arranged entrance surface for an illumination beam path has.
    Reticules are provided in the observation beam path of optical observation and aiming devices, in particular riflescopes. The applied on the carrier foreseeable target mark is referred to as a line image. When hunting at dawn or dusk, the line image is often not visible on the dark game body. Therefore, various solutions for illuminating the line image have been proposed. Thus, it is known to etch the line image in the form of a glass plate carrier and filled with pigments. Illumination with a light source highlights it brightly from the background due to light scattering and light diffraction of the filling material. However, in the known reticle only a very small part of the light is deflected in the direction of the observer. According to EP 0 886 163 B1, a diffraction grating which is applied to the carrier is therefore used as the line image. The fact is exploited that according to the diffraction theory, the first diffraction order has a particularly high light intensity. Thus, although the brightness of the illuminated line image is slightly improved, but the light is not uniformly emitted, that is, the brightness is dependent on the viewing direction. Also, only a very small part of the introduced light power is deflected in the viewing direction.
    Furthermore, it is known from DE 10 051 448 A1 to enclose the carrier with a light guide, which is illuminated by the light source. Since the light is scattered in a too large solid angle, the energy consumption is considerable for a sufficient brightness. According to DE 29 903 989 U1 a line image, namely a target mark in the middle of the reticle, in a further, applied to the carrier line image in the form of a reticle of a laterally arranged on the reticle projection device via a beam splitter in the observation beam path projected onto the carrier. As a result, although a bright line image is achieved, but the space requirements and weight are significant. In addition, the light transmission is reduced by the splitter layer between the two prisms of the beam splitter. Also, it is difficult to adjust the two line images to each other. From EP 0 718 585 B1 a reticle is known, which has a lighted ring with bars as a target mark, which are provided with a reflection surface at the top to form illuminated points.
    A device of the aforementioned type has become known from EP 1 653 271 A1. In order to enable large-area illumination of line images that deviate from a point-like structure, for example annular line images, it may be necessary to use a lighting spread over a larger area. If, in the known solution, such illumination is used, for example in the form of an LED with a diffuser, the luminance in the region of the line image is reduced.
    It is therefore an object of the invention to improve the lighting of line images to the effect that good visibility and high luminance in the region of the line image is ensured even with line images with a deviating from a punctiform structure form.
    This object is achieved by a device of the aforementioned type according to the invention that at least one retroreflector is arranged on the reticle, wherein a reflective layer of the retroreflector faces the reticle.
    The solution according to the invention makes it possible to couple light emerging from the reticule back into the reticule, and to reflect in the direction of the reticule, so that the luminance in the region of the reticule is increased. In addition, light which is not coupled out in the direction of the observer in the region of the line image can be thrown back onto the line image by retroreflection, as a result of which an increased luminance is achieved in the region of the line image. Of course, this advantage also results in a punctiform target. With the solution according to the invention, it is generally possible to substantially reduce the energy required to illuminate the line image or the target mark. It should be noted at this point that the terms target mark and line image are used synonymously in this document.
    A particularly effective light feedback coupling and deflection of the light in the direction of the line image can be achieved by arranging the at least one retroreflector at least on a first side of a plane passing through the line image and normal to the surface of the reticle having the line image, while the entrance surface for the illumination beam path is located on a second side of the plane opposite the first side.
    According to a preferred variant of the invention, it can be provided that the reticule has a first main surface and a second main surface, wherein the first and the second main surface parallel to each other and are interconnected by a lateral surface, wherein a sum of surface areas of the two main surfaces larger is as an area of the lateral surface, wherein the entrance surface for the illumination beam path is formed by a portion of the lateral surface, and wherein the line image is arranged on one of the two main surfaces.
    The lateral surface of the reticule may have a smooth surface. The smooth surface allows good light coupling and good connectivity of the retroreflector with the reticle.
    It has proven particularly advantageous for the retroreflector to be arranged on a section of the lateral surface of the reticle which is different from the section of the entry surface
    It has proven to be particularly advantageous with regard to increasing the luminance in the region of the reticule that the at least one retroreflector is arranged at least on one of the entry surface for the illumination beam path diametrically opposite portion of the lateral surface of the reticle.
    Furthermore, the at least one retroreflector can be arranged on at least one section of the lateral surface of the reticule adjoining the entry surface.
    According to a further variant of the invention, the retroreflector can be arranged on one of the main surface of the reticle opposite the main image having the line image.
    Preferably, the reticule is cylindrical in shape and has a conical-shaped, in particular circular, or a polygonal, in particular rectangular, base surface. In addition, the reticule can be formed from a material which is transparent in visible light, in particular glass or plastic. The term "transparent" in this document is understood to mean that the material used is a material which is transparent in the visible electromagnetic spectral range.
    Furthermore, the retroreflector can be frictionally connected to the reticle by a transparent layer in the visible light.
    According to an advantageous variant of the invention, provision may be made for the retroreflector to have a body, in particular a decoupling prism, which has retroreflecting structures, in particular microprisms.
    It has proven particularly advantageous if the retroreflector is formed by a retroreflector film. The use of a retroreflector sheeting allows a very simple production of the device according to the invention.
    In addition, the film can be brought by appropriate cropping in a simple manner very accurately to the desired size and shape.
    By forming a mirror for deflecting the illuminating beam path (BS) leading from the light source to the line image, which is arranged on the reticule laterally to the surface facing the line image, a compact construction of the telescope equipped with the device according to the invention can be achieved.
    The mirror according to the preferred variant of the invention has two focal points, wherein a mirror surface of the mirror is concavely curved and the light source is arranged on a front side of the mirror in the region of a first focal point and the line image through the directed to a second focus of the mirror Light rays is illuminated.
    Light rays directed to the second focus converge on the main surfaces and on the retroreflector in the region of the line image after total reflection.
    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.
    1 shows a plan view of an optical device 1 for displaying a line image 2. As required, the line of sight on the plane of FIG. 1 (perpendicular to the plane of the drawing) corresponds to the direction of the optical axis of the observation beam path of a telescope equipped with the optical device 1 or riflescope.
    1, the optical device 1 for displaying the line image 2, a reticle 3 and a light source 5 for illuminating this line image 2. The line image 2 is arranged on a surface 4 of the reticule 3. The reticule 3 itself may be cylindrically shaped or have a conical-shaped, in particular circular, or a polygonal, in particular right-angled, base surface. In addition, the reticule 3 is made of a transparent material in the visible light, in particular glass or plastic.
    The line image 2 can be formed by a diffractive and / or scattering microstructure, which is produced, for example, by etching, or by a diffraction grating on the carrier surface. In the case of an etched or incorporated line image 2, a filling material made of pigments can be introduced into the depression formed, so that the line image 2 stands out brightly from the background upon illumination with the light source due to light radiation and light diffraction on the pigments. Photoluminescent pigments, e.g. emit visible light under UV irradiation.
    The line image 2 can also consist of alternately arranged transparent gaps and light-impermeable webs. The ratio of the width of the webs to the width of the gaps is preferably greater than or equal to 1: 1. The pitch period of the amplitude grating depends, according to the diffraction formula, on the wavelength of the light, the angle of the incoming and outgoing light and the refractive index of the air and the material of the carrier.
    Laterally to the surface 4 having the line image 2, a mirror 6 for deflecting a light beam path leading from the light source 5 to the line image 2, indicated by the reference symbol BS in FIG. 2, is arranged on the reticule 3. The mirror 6 may be glued to the reticule 3.
    According to FIG. 2, the reticule 3 has an entrance surface 7 for the illumination beam path BS arranged laterally to the surface having the line image 2. As can be seen from FIG. 2, according to the invention a retroreflector 9 is arranged on a light exit surface 8 of the reticule 3. A reflection layer of the retroreflector 9 in this case faces the reticule 3. A retroreflector is understood as meaning a reflective material which reflects the incident radiation largely independently of the orientation of the reflector back toward the radiation source. Retroreflektoren are in large numbers, for example from US 5,764,413, known.
    The retroreflector 9 preferably has a reflective layer with retroreflective structures formed from microprisms or microglass spheres, it being possible for the reflective layer to be provided with a planar surface which is transparent to visible light.
    Furthermore, the retroreflector 9 is arranged on a first side a of a plane ε extending through the line image 2 and normal to the surface of the reticule 3 having the line image 2. The entrance surface 7 for the illumination beam path BS is located on a side a opposite, second side b of the plane ε. In addition, the retroreflector 9 can be frictionally connected to the reticule 3 by a layer transparent in the visible light. To connect the retroreflector, for example, an adhesive, for example, UV-curing acrylates, or epoxy resins, etc., can be used.
    The retroreflector 9 may be formed by a retroreflector sheeting, as shown in FIG.
    As can also be seen from FIG. 2, the reticule 3 has a first main surface 10 and a second main surface 11. The first main surface 10 and the second main surface 11 extend parallel to one another and are interconnected by a lateral surface 12. The lateral surface 12 of the reticule 3 may have a smooth surface.
    A sum of the surface areas of the two main surfaces 10, 11 may in this case be greater than an area of the lateral surface 12. The entrance surface 7 for the illumination beam path BS is formed by a portion of the lateral surface 12. The retroreflector 9 is arranged on a section of the lateral surface 12 of the reticule 3 that is different from the section of the entry surface 7. The retroreflector 9 is arranged in the illustrated embodiment at one of the entry surface 7 for the illumination beam path BS diametrically opposite portion 13 of the lateral surface 12 of the reticle. However, this arrangement is not mandatory, so the retroreflector 9 can be quite generally arranged on a adjoining the entrance surface 7 portion of the lateral surface 12, exits at the light generated by the light source 5 from the reticule 3, the retroreflector 9 can also with the exception the entrance surface 7 include the entire lateral surface 12.
    The line image 2 is arranged on the main surface 10 in the embodiments shown in FIGS. 2-5.
    The mirror 6 has two focal points, wherein a mirror surface of the mirror 6 is formed concavely curved. The light source 5 is arranged on a front side of the mirror 6 in the region of a first focal point of the mirror 6. The light beams directed toward a second focal point 14 of the mirror 6, which form the illumination beam path BS, illuminate the line image 2.
    To clarify the geometric relationships of the light source 5, the mirror 6 and the mentioned second focal point 14, an ellipse enclosing the curved mirror surface of the mirror 6 is indicated by a dashed line in FIGS. 2 to 5. The two foci of this ellipse coincide with the light source 5 on the one hand and with the said second focal point 14 of the mirror 6 on the other.
    The light beams directed towards the second focal point 14 after reflection at the mirror surface of the mirror 6 converge after total reflection at the main surface 11 in the area of the line pattern 2 arranged on the other main surface 10. A part of the light arriving at the line image 2 emerges from the reticule 3 and is emitted from the line image 2 into the observation beam path of the telescope. This due to the interaction with the pigments forming the line image 2 or the diffraction grating. That part of the light which remains on the main surface 10 in the reticule 3 by total reflection is successively reflected on the main surface 11, on the retroreflector 9 and again on the main surface 11, and then also converges and stands in the region of the line image 2 in addition to its lighting available. In this way, the luminance in the region of the line image 2 is substantially increased.
    By focusing the light on the line image 2, a line image with high luminance is obtained. For a uniform brightness distribution over the viewing angle, the light emerging from the line image 2 preferably has the same aperture angle as the downstream viewing optics, ie the eyepiece. This is achieved by the mirror 6 and its interpretation together with the diffraction grating.
    The line image 2 emits the light of the laterally arranged light source, preferably perpendicular to the main surface 11 of the reticule 3. With a diffraction grating, however, other angles than 90 degrees are possible. It should also be noted that the rays exit at a certain opening angle.
    Referring to Figures 3 and 5, the retroreflector 15, 16 may also include a body 17, 18 which may be in the form of a decoupling prism for coupling light from the reticle. The body 17,18 can be made for example of glass or plastic. A retroreflector sheeting may be adhered to the body 17, 18. As an alternative to adhering a retroreflector sheeting, however, a reflective layer of retroreflective structures can also be introduced or molded directly into the body 17, 18. In the examples shown in FIG. 3 and FIG. 5, the reflection layer of the respectively illustrated retroreflector 15, 16 is inclined relative to the main surfaces 10, 11 of the reticule 3. The reflection layers of the retroreflector 15, 16 are preferably arranged in a vertical position relative to the main propagation direction of the light incident on them. This can optimize the effect of retroreflection.
    In the example shown in FIG. 4, the retroreflector 9 is arranged on the main surface 11, which is opposite to the main surface 10 with the line image 2.
    FIG. 6 shows an alternative embodiment of the device 1. In this case, the entrance surface 7 for the illumination beam path BS (FIG. 2) has a planar surface in which the reticule 3 or its lateral surface 12 is flattened in the region of the mirror 6. This is achieved, for example, in that the vitreous body forming the reticule 3 is ground off flat. In this way, the prism body or the mirror 6 can be easily connected to the reticule 3. This connection takes place, as usual with glass bodies, by so-called cementing. On the other hand, it can also be provided that, as shown in Fig. 6, and the light-emitting surface 8 is formed on the lateral surface 12 of the reticule 3 planar. In the case of a retroreflector 9 formed by a retroreflector sheeting, a planar connection point or adhesive surface is thus available to it.
    Fig. 7 shows a further embodiment of the device 1 in sectional view. In this case, in the illumination beam path BS between the light source 5 and the reflective surface of the mirror 6, a lens 19 and a diffuser is arranged. In this way, the illuminated surface area on the main surface 10 in the region of the line image 2 is widened or enlarged. As a result, even when using a more complex or larger-scale line image, instead of only a single centrally located point as a target uniform illumination can be achieved. In addition, the luminance of the line image 2 is markedly increased by the retroreflector 9 arranged diametrically opposite the entrance surface 7 of the illumination beam path BS.
    The use of the reticule 3 according to the invention with a retroreflector 9, 15, 16 arranged thereon has in each of the exemplary embodiments described the effect of a more uniform illumination of the line image 2, which can thus be represented to the viewer in all its parts as uniformly as possible.
    Fig. 8 shows a cross section of a device 1 according to another embodiment. In this device 1, the mirror 6 for deflecting the light of the light source 5 in the reticule 3 through the entrance surface 7 through a plane mirror or reflection surface. To generate a convergent beam path toward the line image 2, a lens 20 is arranged between the light source 5 and the mirror 6. The arranged at the light exit surface 8 and the opposite side of the lateral surface 12 retroreflector 9 in turn ensures that in the region of the line image 2 in the interior of the reticle 3 totally re inflected light is reflected back to the main surface 10 with the line image 2.
    A further alternative embodiment of the device 1 for displaying the line image 2 of a target mark is shown in FIG. 9. In this case, the light of the light source 5 after bundling through the lens 20 obliquely incident on the main surface 11, where a first total reflection occurs. To achieve this obliquely incident beam path, the light source 5 and the lens 20 are also arranged obliquely and laterally on the reticule 3. An optical axis 21 of the illumination beam path BS in the region of light source 5 and lens 20 is aligned in alignment with the main propagation direction of the light on the main surface 11 out. The entrance surface 7 for the illumination beam path BS is formed by a plane produced by grinding on the reticle 3 forming the glass body, planar surface. The entrance surface 7 is also aligned perpendicular to the optical axis 21 of the light source 5 and the lens 20. In the same way, the entrance surface 7 opposite light exit surface 8 may be made on the reticle 3.
    Alternatively, the entrance surface 7 and the light exit surface 8 may be realized by a separate body, as described in the bodies 17,18 in the embodiments of FIGS. 3 and 5.
    10 shows a plan view of the device 1 for displaying the line image 2 of a target in a telescope according to a further embodiment. The entrance surface 7 of the illumination beam path BS is formed on the reticule 3 planar, wherein at the entry surface 7, a lens 19 is arranged or attached to produce a diffuse beam path of the light of the light source 5. This entry surface 7 can be made as a plane or planar surface on the glass body of the reticle 3 ground point. The entrance surface 7 is also aligned parallel to the optical axis of the observation beam path (i.e., perpendicular to the plane of the drawing of Fig. 10). By virtue of the retouch reflector 9 arranged opposite the entry surface 7, the luminance in the region of the line image 2 on the surface 4 of the reticle 3 can be increased.
    11 shows an alternative device for displaying a line image 2 in longitudinal section with respect to the optical axis 21 of the illumination beam path BS. In this variant of the representation of a line image of a target, the image of the line image 2 is coupled by means of projection optics (not shown) with an optical axis 22 and after deflection by a coupling prism in the observation beam path of the telescope. The reticule 3 is located outside the observation beam path of the telescope. The line image 2 is generated by a mask 23 which is mounted on the reticle 3. For this purpose, the mask 23 physically contains a negative of the line image 2, wherein elements of the line image 2 forming points transparent, other areas of the mask 23, however, are opaque. The mask 23 is realized for example by selective vapor deposition of the reticle 3 forming the glass body with a metal. This reticule 3 with the mask 23 is illuminated by means of the light source 5 and a condenser lens 20. According to this embodiment, the device 1 has a retroreflector 24, which is formed annular disk-shaped and symmetrical with respect to the optical axis 21 of the illumination beam path BS, preferably in the region of the condenser lens 20, is arranged. The arrangement of this retroreflector 24, the radiation density in the region of the line image 2 and the mask 23 and thus the light output can be increased.
    A modification of the embodiment of the device 1 according to FIG. 9 is finally shown in FIG. 12. The arrangement of the entrance surface 7 on the reticle 3 on the one hand and the light source 5 with the lens 20 on the other hand provided in such a way that the main propagation direction of the light coming from the light source 5 directly on the first main surface 10 or directly to the line image is aligned. The optical axis 21 of the light source 5 and the lens 20 comprehensive lighting device is aligned directly on the line image 2 out. Corresponding to this design of the entrance surface 7 on the reticule 3, the light exit surface 8 of the entrance surface 7 is arranged diametrically opposite to the illumination beam path BS. In this case, the light exit surface 8 is preferably oriented vertically with respect to the direction of the light reflected by the first main surface 10.
    It goes without saying that the embodiments shown in the figures can be combined with one another, and retroreflectors can be attached to several places on the reticule 3.
    For the sake of order, it should finally be pointed out that for a better understanding of the construction, elements have been shown partially unevenly and / or enlarged and / or reduced in size.
