We present information on a newly constructed optical calibration facility developed specifically for testing and calibration of low-light devices, including auroral imagers, photomultiplier tubes, star sensors and other instruments. A combination cleanroom/darkroom is utilized to isolate instruments from airborn particulate and from stray light. One of the key components of the calibration facilty is a custom integrating sphere that provides a uniform light source for imager calibration with an intensity range comparable to weak to strong auroral emissions. Capabilities also include a monochromator to characterize spectral responses of optical systems with up to 0.1 nm resolution, a collimator that provides the capability for viewing low-light test patterns focused at infinity, and other supporting hardware. The selection of test slides currently available for use in the collimator are well-suited for characterizing parameters such as point spread function, modulation transfer function, spatial resolution, distortions, etc. Current applications using this facility include the ePOP satellite (auroral imagers), ROPA rocket (auroral imagers), and the Star Sensor for the IBEX mission (PMT star sensor). In this presentation, results are shown from calibration tasks associated with these instruments.
