ABSTRACT:
An improved optical projection viewing system is provided with a novel wide projection angle relay projection lens and a novel magnifying biocular viewing lens. The magnifying biocular viewing lens has non-symmetric front and rear biconvex surfaces having a uniform field distance when viewing the entire image on the viewing screen. The biocular viewing lens has positive distortion and color separation which is compensated for by negative distortion and color separation provided in the relay projection lens.
