Abstract

PURPOSE: To provide an optical system of a large aperture and of a wide angle of view while improving the forcusing function over the whole angle of view by arranging an aberation compensating plate, which has its both surfaces formed into a non-circular shape of special relationship, in a preset position at the side of the reflecting surface of a concave mirror.
