Abstract

The sighting objective has the light beam (1) falling onto the 45 deg. surface of a total reflection prism (2). The beam passes downwards through a double lens comprising a convergent biconvex lens (A) and a divergent biconcave lens (B). The beam passes through a diaphragm (3) iris and falls onto a meniscus (C) and a semi-reflecting 45 deg. flat lens (4). Part of the beamn is directed to another double lens comprising a concave convex meniscus (D) and another similar (E), passing onto the film (5). The remaining beam continues through a concave convex meniscus (7) to a photo-electtric cell (6).
