Abstract

A mid-wave infrared imaging guiding system with high resolution is designed. First imaging refractive system and telephoto lens groupe are used for the initialized structure. The system with three optical elements, the all field of view of 10°, a focal length of 70 mm, and the total length of 49 mm is designed. Within -40°C~60°C, the system possesses better athermal performance. The image quality of the system almost approaches the diffraction limit. The biggest defocused spot's diameter is less than 15 μm. It is applicable to the infrared focal plane arrays(IR FPA) detector with the format of 640×512, the pixel size of 15 μm and the Fnumber of 2. This system can suffice the requirements design of infrared seeker, which has the advantages of high resolution, wide field and small volume.
