    • 专利摘要:
    The invention relates to an optical system for spectral devices which improves the resolution of a spectral line image up to the edge portions by use of at least two collimators. The collimators are adjacently located in direction of dispersion and differently inclined relative to the plane of dispersion of the optical system. The produced spectral sections are imaged on a detector where the number of the collimators used depends on the number of spectral sections.

    专利说明:

    The invention relates to the field of spectral instrumentation, more specifically relates to optical systems for spectral instruments.
    Optical systems are known for spectral devices (see, for example, KI Tarasov. Spectral devices, L, Mashinostroenie, 1977, p.143).
    Such spectral instruments with these optical systems are distinguished by an insufficient resolution at the edges of the spectrum.
    The closest technical solution can be considered as an optical system for spectral instruments containing along the beam at least one light hole, two collimators, a dispersing element, the collimators being located next to each other in the direction and dispersion of the dispersing element, a camera lens and at least one receiver located in the meridional focal plane of the optical system (see US Patent No. 3985441, Cl. 356/99, 1976),:
    A disadvantage of such optical systems is the reduced resolution at the edges of the spectrum.
    The purpose of the invention is to provide sufficient resolution at the edges of the spectrum without reducing luminosity.
    This goal is achieved by TeMj that in the optical system for spectral devices containing at least one light hole, two collimators, a dispersing element along the beam, the collimators are located next to each other in the direction of dispersion of the dispersing element, a camera lens and at least one receiver located in the meridional focal plane of the optical system; collimators are located perpendicular to the direction of dispersion and slope

    different angles that provide the corresponding spectral regions on the receiver or radiation receivers.
    1 shows a general view of the optical system from above; figure 2 - General view of the optical system; on fig.Z - view of the spectral lines of two parts of the spectrum.
    In FIG. 1.2, the following notation is accepted: entrance slit 1, collimator mirrors 2.3, diffraction grating 4, dispersing rays 5.6, camera mirror 7, receiver 8.
    The device works as follows.
    Radiation from the entrance slit 1 falls on the mirrors of collimators 2 and 3, located perpendicular to the direction of dispersion and inclined at different angles, which display the corresponding spectral regions on the receiver or radiation receivers. The light from the collimators falls on the diffraction grating, which decomposes the radiation into the spectrum indicated by paraxial rays 5,6. The dispersed light flux falls on the mirror of camera 7, deflecting them to the plane of the receiver 8. The mirror of camera 7 displays beams with different wavelengths at different heights as two adjacent spectral regions one above the other on a flat receiver 8.
    . By choosing the curvature of the mirrors of collimators 2 and 3 and the oC and ci angles, you can determine the position of the best coma correction in both spectral regions. However, the invention is not limited to the use of two collimators and, therefore, spectral portions displayed on top of each other on a flat receiver.
