Infrared lenses are designed with focus 50mm, wave band 8~12μm, Fnumber 0.8 and field of view 10° to meet the need of uncooled focal plane array(UFPA) sensor. A fourpiece all refrative and a threepiece hybrid refractivediffractive infrared lenses are designed. From the result the latter is lighter than the former and its image quality simultaneity excel the former.
