Very Long Wavelength Infrared Filters
DSI’s line of very long wavelength IR optical coatings are available in narrow and wide bandpass (NBP and WBP) filters, long- and shortwave pass (LWP and SWP) filters, and antireflection (AR) coatings.
VLWIR Coatings can be applied to a variety of substrates, including germanium (Ge), zinc selenide (ZnSe), silicon (Si), and indium antimonide (InSb). Edge placement, transmission blocking ranges and levels, and operating temperatures and angles can all be customized per specifications.
Deposition Sciences’ VLWIR filters are ideal for remote sensing, chemical analysis, astrophysics/astronomy, and horizon sensors.
