Temperature change could cause the degradation of imaging quality of infrared optical system.In order to improve the adaptability of airborne infrared optical system and ensure steady image quality of the infrared optical system in complex airborne environment,an athermalization design of dual field infrared optical system was proposed.The key technical indexes and requires of this system are given,and the theory and realization method of the system are explained.Zoom theory and athermal technology are applied in this system.
