System aspects of filter radiometer optics used to sense planetary atmospheres are described. Thus the lenses, dichroic beamsplitters and filters in longwave channels of the Mars Observer PMIRR Pressure Modulator Infra Red Radiometer instrument are assessed individually, and as systems at 20.7 tim, 31.9 tim. 47.2 m wavelength. A window filter and a longwave calibration filter of the SCARAB earth observer instrument are assessed similarly.
