Paper Abstract

The design and manufacture of dielectric-film interference filters for cooled. FIR astronomy is described. The bands are 16.5-21.5 μm, 17.5-19.5 μm, 19.5-21.5 μm and 27 μm cut on. The films are PbTe/CdSe and the substrates are CdTe (some 12 mm thick), without absorption in the region: KRS-6 films are used for antireflection.
