ABSTRACT:
An optical system comprises a pentagonal roof prism and a transparent plate. A rear surface of the pentagonal roof prism is provided with a triangular recessed portion. The wall of the recessed portion is frosted. The transparent plate is a triangular plate, slightly smaller than that of the recessed portion, and is applied to the wall of the recessed portion. The obverse face of the transparent plate is a transparent or polished surface. The transparent plate is applied to the recessed portion with adhesive having photo-transmissibility. It is preferable that the adhesive does not shrink when hardening.
