Abstract： To achieve wide-area detection of space targets， we design an optical system with a broad spectrum range （ 400～1000nm ）， a large field of view （61∘） ）， a smallF-number （1.38）， and low distortion. This optical system is capable of detecting space targets with a magnitude of 6， enabling wide-area detection for space targets. Initially，a mapping between the radiation model of space target detection and the optical system parameters is established. The optical design is then theoretically analyzed using a reverse telephoto layout as the initial design configuration. The design is optimized to balance and correct the severe chromatic aberration resulting from the large field of view and wide spectral range， while improving enclosed energy and considering the roundness of scattered spots.Finally，The detection capability is verified through space optical simulation experiment and physical experiment. The results show that the optical system meets the wide-area detection requirements for space targets with a magnitude of 6.The overall design of the optical system is reasonable and compact， meeting the requirements of wide-area detection of space targets.
