Satellite solar band calibration source target apparatus

摘要

The present invention is an off-axis collimator used to monitor the optoelectronic performance of a radiometer, which off-axis collimator is comprised of a single off-axis paraboloidal mirror, a broadband radiant energy source housed in an integrating sphere, detectors for monitoring the performance of the broadband radiant energy source, and a housing for the collimator.
