Abstract:

Several Infrared IR imaging systems have been measured looking down a collimator and a standalone large surface blackbody. They were both focused and had the same total atmospheric path length between source and sensor, yet discrepancies were noticed in that the standalone blackbody measurements were providing more perceived flux even when compensating for vendor provided collimator transmission losses. This report provides the background and discusses the methodology used to measure the actual losses in a collimator.
