[Abstract]:In order to realize the optical passive non-thermal design of a large variable ratio continuous zoom infrared optical system, In this paper, the basic theory and method of non-thermal design for continuous zoom system are studied. The method of optical passive thermal difference in large relative aperture and large variable ratio continuous variable focal length infrared system is put forward, and the continuous zoom length is deduced. A method for calculating the optical passive thermal difference of the system. Based on this method, A system with a focal length of 30 ~ 150mm, a long wave working band of 12 渭 m with a relative aperture of 1: 1.1, and a continuous zoom system with a large relative aperture is designed, and the optical passive heat dissipation difference is designed. The MTF of the system is greater than 0. 3 in the temperature range of -30 鈩，
