Abstract
High transmission, low pass scatter filters for blocking at wavelengths from 3.5 μm to 50 μm and single-layer antireflection coatings for optical materials used in the 25-μm–300-μm region of the spectrum are described. The application of both techniques to liquid-He-cooled filters permits the construction of efficient low pass and medium-width band pass filters for use throughout the far infrared.Keywords
