Abstract
An optically passive athermal infrared optical system working in the 8 - 12 micron long wavelength infrared band was designed by using a special infrared optical material AMTIR (amorphous material transmitting infrared radiation). The design principle, design results are described in this paper. In addition, the optical system was incorporated with an infrared focal plane array forming an infrared camera. The thermal test of imaging quality of this camera is also presented.
