Abstract: Based on the requirements of miniaturization and light weight for airborne optic systems, IR and TV system were designed with the common light path. For the 640480 uncooled focal plane array,an infrared long wave system was presented with a focal length of 185mm, field of view (FOV)of 5.8, F number of 1.3. For the 1/3 charge coupled device (CCD)(4.8 mm 3.6 mm,759 596pixels), a visible（TV） system ,which had 86mm focal length, 4 FOV and 4.5 F number, was completed.
