Custom infrared coatingsFrom Andover
Andover Corporation offers optical coatings for the long wave infrared band, on substrate materials such as Germanium, Zinc Selenide, Zinc Sulfide, Silicon, Sapphire and chalcogenides. Coating types include AR, bandpass, long and short pass, dichroic, and more. Andover can also design infrared coatings to function as dichroics, reflecting one region while allowing the transmittance of another. While generally operating at 0° or 45°, the coatings can be optimized for any particular angle or range of angles of incidence. Also available are custom dichroics that transmit visible and far infrared light simultaneously.
