Abstract: The present invention discloses a polarization-maintaining reflector arrangement comprising a reflector group including at least one polarizing reflector and at least one compensating reflector, wherein the incident plane for the polarizing reflectors is perpendicular to the incident plane for the compensating reflectors, and the product of s-wave reflectance of all the polarizing reflectors and p-wave reflectance of all the compensating reflectors is equal to the product of s-wave reflectance of all the compensating reflectors and p-wave reflectance of all the polarizing reflectors. One or more reflector groups can be used in the light path. The invention can conveniently and effectively eliminate the polarization caused by reflection.

Abstract: The invention discloses a low stray light polychromator comprising an optical housing, an entrance slit, a dispersion system and an array detector. The dispersion element of the dispersion system is a grating. A photosurface of the array detector is obliquely intersected with a principal section of the grating. In the invention, by changing the relative operation of optical elements in the polychromator, the stray light generated by the unexpected reflection on the photosurface of the array detector is exactly reflected out from the expected optical path. In addition, on the inner wall of the optical housing, small diaphragms for extinction are disposed in a plane in which reflection faculaee are projected, thus stray light will be reduced greatly.
