Antireflection coating optical elements in the 2.5-3.5-μm spectral region

The optimum regimes for depositing antireflection coatings based on amorphous silicon and silicon monoxide are determined in this paper for the 2.5-3.5-μm spectral region with the minimum losses to absorption. These regimes can be used for fabricating both antireflection coatings and interference filters and mirrors.
