[Abstract]:An infrared optical system with long focal length and large magnification ratio in four view field is designed. The optical system consists of anterior fixation group, variable focus group, intermediate compensation group, posterior fixation group, mirror 1, mirror 2 and relay group. The optical system can not satisfy the long focal length, large ratio of variation and miniaturization of optical system by using optical compensation superposition mechanical compensation method to overcome the single optical compensation or mechanical compensation zoom mode can not satisfy the long focal length of optical system at the same time. The temperature compensation of optical system in the wide temperature range (-40 鈩，
