RAD-900 Infrared Radiometer
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.
