Paper Abstract

According to the athermalization theory a optical passive athermalization stepping-zoom dual FOV MWIR system in 3μm~5μm designed in this paper, Through the rational combination of infrared optical materials and aspheric surface realized the design of optical passive athermalization. The optical system only use five lens and the optical materials is commonly such as germanium, silicon and Znse. The focal length is 90mm/150mm, the total length is 139mm. The MTF of the two fields are ≥0.5@16lp/mm at -45°C~+60°C, which shows its optical performance approximates to the diffraction limit.
