Temperature chamber FLIR and missile test system

In this paper, we present a methodology for testing Forward Looking Infrared (FLIR) Systems and Missile Seekers in a temperature chamber from -35 to +72 C. Test results show that a single material projection collimator has little to no defocus in this wide temperature range. Blackbody technology is such that a blackbody reference source also shows little to no degradation over this entire range. This technology is a cost saving method which is an alternative to using a collimator system outside of the thermal chamber with a window.
