OPTICAL REFLECTOR Russian patent published in 1995 - IPC

FIELD: optical instrument engineering. SUBSTANCE: unlike spherical surfaces are used with equal radiuses of curvature for connecting elements of double-prism reflectors, which have two prisms. One prism has double-faced rectangle angle in form of a roof, and the other one has single reflecting face. Spherical surfaces are made in form of lenses either and are applied onto leg surfaces, which are turned one to the other, or are applied onto leg surfaces of prisms. As a result, errors may be corrected during process of making of reflectors due to sliding spherical surfaces one along the other during process of cementing lenses. EFFECT: improved efficiency of operation. 2 cl, 2 dwg
