A single view-point catadioptric long infrared panoramic lens was designed with codeV. The system consists of a hyperboloid mirror and a conventional perspective imaging lens. The hyperboloid mirror enables the lens to obtain a large field of view, the conventional perspective imaging lens projects the virtual image formed by the mirror group onto the detector. The effective focal length is 1.4mm，the relative aperture is 1:1, field of view is ±10°~±90° in vertical direction and 360° in horizontal, the wavelength spectrum is 8-12μm, only Znse and Ge were used in this system. The lens has the characteristics of single view-point, large field view and getting perspective image straightly. Result shows that the modulation transformation function at 17/mm is greater than 0.7, which proves that the image quality of the optical system is good.
