Deposition Sciences Intros Very Long Wavelength IR Filters
Very long wavelength IR filters.
Santa Rosa, CA — Deposition Sciences, Inc. (DSI
), manufacturer of highly durable thin film optical coatings, has introduced a new line of very long wavelength infrared (VLWIR) filters. The filters provide high transmittance over the 12µ to beyond the 22µ wavelength region. Utilizing the company's high precision physical vapor deposition (PVD) process, these robust coatings readily pass all environmental tests and can be repeatedly cycled between ambient and cryogenic temperatures, without degradation.
The company'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.
The VLWIR filters are suitable for remote sensing, chemical analysis, astrophysics/astronomy, and horizon sensors.
