Abstract

A dual field of view and zoom infrared optical system with uncooled infrared staring focal plane arrays is designed in this paper. The operating waveband of the system is 8~12μm, and zoom radio is 3×. The optical configuration is based on the axial motion of a lens group along the optical axis. Optical material used infrared monocrystalline silicon, Znse, In order to achieve high performance, high image quality, used two even aspheric surfaces in this system. The advantages of this system are the high imaging quality, small volume, lightweight.
