A small device consisting of a lamp, filter, and external photodiode has been used successfully to monitor the sensitivity of a Lyman-alpha photometer on OGO-6 as well as a number of Air Force satellites. The operation of this calibration device is independent of lamp, filter, or window decay. (Author)
