ABSTRACT:
A multiple element lens system for projecting images generated from curved surfaces. A spherical projection lens is provided along a projection axis. An aspheric plate follows the spherical lens, which is followed by a second spherical projection lens. Parfocalizing separate curved image surfaces of different primary colors permits a narrow spectral bandwidth lens system, having an improved speed and resolution, providing combined full color projected images.
