The RAD-900 Infrared Radiometer makes precise measurements of radiometric temperature and
spectral radiance. It operates in the both the MWIR and LWIR bands and may be used to carry out
both 1D and 2D source radiance measurements when installed on the ASB-920 Angular Scan Base.
Through its calibration, the RAD-900 provides traceability to national standards and to the International
Temperature Scale. Most thermal Target Generators are factory calibrated to provide precise physical
temperature differences between their foreground and background, but the reflective or refractive
collimators with which they are typically paired attenuate the radiation from these target generators,
making the thermal contrast of the target appear smaller than the physical difference.
The RAD-900 provides an accurate means to perform a radiometric calibration for a thermal target
generation system by accurately measuring the radiometric temperature difference of the target as a
function of the physical temperature difference. In this role, it is an essential component of a complete
thermal imager testing laboratory.
