  • The composition of novel chalcogenide infrared glass are introduced in this paper. Compared with other infrared glass, its advantages are analyzed. Mathematical model of relation between the temperature and other parameters in infrared detection imaging system is established. Benefitting from the less index temperature coefficient and low cost of chalcogenide infrared glasses, a refractive mid-wave infrared(MWIR) detection thermalization imaging system is presented. The design results indicate that the system has good imaging quality at the temperature of -40 ℃, 20 ℃ and 60 ℃.The system is compatible with staring focal plane array MWIR detector with 320 pixel256 pixel and pixel pitch of 30 m30 m.
