ISOPHOT: far-infrared imaging polarimetry and spectrophotometry on ISO

摘要

Abstract: ISOPHOT is one of four instruments onboard the ESAInfrared Space Observatory scheduled for launch inSeptember 1995. It covers the wavelength range 2.5$mu@m to 240 $mu@m with wide and marrow spectral bands.Diffraction limited observations as well as wide beammeasurements of faint extended sources are possible.Polarimetric observation can be made over the wholewavelength range. The minimal detectable flux isapproximately 10 mJy. The astronomical areas to beaddressed range from solar system objects tocosmology.!6
