A four-channel far-IR photometer designed for use with a balloon-borne 102-cm telescope is described. The data analysis system for this photometer is discussed, and a typical observational program is outlined. Possible objects that may be observed with the four-color far-IR photometer include molecular clouds, the galactic-center region, H II regions, quasars, Seyfert galaxies, and BL Lacertae objects.
A far-infrared photometer has been developed as a focal plane instrument for a balloon-borne 102-cm telescope. The four gallium-doped Ge bolometers adopted for the system operate at 1.8 K in a liquid-helium dewar. Wavelength bands of the four-bolometer system are a narrow spectrum between 18 and 22 microns, and bands centered at 42, 70, and 140 microns. The responsivity and Johnson noise of the detectors limit the performance of the instrument.
