This report describes an instrument for protecting sensitive infrared detectors, such as those used in satellites, from being damaged by exposure to high intensity radiation. The high intensity radiation may come from a high power cw laser. A gas absorption cell is used between the detector and the collecting optics to limit the amount of radiation reaching the detector. However, if it is desirable to also protect the collecting optics, then the gas absorption cell may be used in front of the collecting optics.
