Abstract

The invention comprises an adapter having a set of four mirrors in two pairs located in front of a camera lens. The outer two mirrors face generally outward along the optical axis of the lens and the inner two mirrors face generally inward into the lens. The centers of the outer two mirrors are spaced apart by an appropriate interocular distance. The two inside mirrors are together large enough to cover the complete viewing area of the lens, each taking exactly half of the lens viewing area. The two outside mirrors are bigger then the inside pair and large enough to cover the viewing area of the inside pair to avoid viewing area reduction. The convergence of the two outer mirrors is adjustable by swiveling them simultaneously and equally about their centerlines with a ganging mechanism. The two center mirrors may be fixed, or could be adjustable by being swiveled so that one side of each remains in tight contact with the other along the optical axis of the camera lens, and each makes a 45.degree. or lesser angle to the optical axis. The whole assembly is to be housed in a dust and light proof housing that mounts onto the lens.
