Abstract
Three folded Maksutov/Bouwers telescopes formed in a single housing to provide focused images from three angularly spaced fields of view. The fields of view are positioned 30.degree. from a central axis and are spaced 120.degree. apart in azimuth. Light enters the telescopes through a common upper aperture, in which a concentric corrector is installed, is reflected from a common lower plane mirror and from one of three inclined mirrors into one of three spherical primary mirrors. The spherical mirrors focus the respective beams onto three focal planes located outside the housing, through openings in the respective inclined mirrors. The concentric corrector compensates for spherical aberration in the spherical primary mirrors, without the need for holographic optical elements, resulting in a simple, compact, lightweight and low-cost device.
