Wide-spectrum and wide-field optical system

The invention discloses a wide-spectrum and wide-field optical system. The wide-spectrum and wide-field optical system sequentially comprises a first battery of lenses (1) placed on the object side, a second battery of lenses (2) placed closer to the image surface than the first battery of lenses (1) and a beam splitter prism (3) placed closer to the image surface than the first battery of lenses (1) and the second battery of lenses (2) from the object side to the image surface. The wide-spectrum and wide-field optical system solves the problems that a satellite optics loading optics system (wide spectrum and wide field) is high in aberration correction difficulty of the field curvature, chromatic aberration and the like, high in processing cost and the like.
