Request InfoDeposition Sciences Inc. (DSI)Our Very Long Wavelength Infrared (VLWIR) Filters provide high transmission in the 12-22 micron wavelength region and are ideal for use in applications involving horizon sensors, chemical analysis, remote sensing, and astrophysics/astronomy. These filters can be repeatedly cycled through ambient and cryogenic temperatures, a key feature because they are typically used at 25 Kelvin to filter out background IR noise. 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,...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/3/2022Two-color Sandwich DetectorsTwo-color Sandwich Detectors from OSI Optoelectronics Inc. are designed for optical remote temperature measurements.
