| Summary: | The invention relates to a free-form surface off-axis three-mirror optical system, which comprises: a main reflecting mirror on which light rays from an object are reflected to form a first reflected light beam; a secondary reflecting mirror, wherein a first reflection light beam which irradiates the secondary reflecting mirror and is reflected to form a second reflection light beam; a third reflecting mirror, wherein the second reflection light beam which penetrates through the incident light beam of the main reflecting mirror, then irradiates the third reflecting mirror and is reflected to form a third reflection light beam; an aperture diaphragm which is arranged on the secondary reflecting mirror; and an image surface, wherein the third reflection light beam penetrates through the incident light beam of the main reflecting mirror, does not penetrate through the second reflection light beam and finally reaches the image surface for imaging, and the image surface and the main reflecting mirror are located o |
