In order to achieve the multi-band and multi-field of view imaging for target and to meet the needs of target detection for large amount of information,a common-aperture visible light/long-wave infrared(VIS/LWIR)imaging optical system with muti-field of view was designed.In this paper,the aperture is 400mm,the working wavelength is 500~700nm and 7.5~10μm,the temperature range is-15□~+50□ this system can realize 1500mm and 3000mm dual focal length(VIS),the full field of view of short focal length is 1.16° and long focal length is 0.58° respectively,and realize 1400mm focal length(LWIR)and the full field of view of 0.54°,satisfy 100%cold shield efficiency.
