Request InfoDeposition Sciences Inc. (DSI)Using proprietary MicroDyn reactive sputtering technology, Deposition Sciences Inc. has developed a durable and abrasive-resistant wide-acceptance-angle bandpass filter that can be coated on curved surface lenses. The thin-film coating blocks wavelengths from the visible into the short-wave IR band, from 400 to 1200 nm, with transmission at 1064 nm. It enables uniform optical performance on the center area of a lens at normal incidence and performance on the edge at high angles of incidence. The filter is designed for use across a large cone angle and engineered for applications that require...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/26/2022Optical MountsThe E-Series of Adjustable Size Kinematic Optical Mounts from Edmund Optics Inc. can be used for mounting a wide range of round, rectangular, and square optical components, including round and...Photonics.com 3/8/2024Motor Control BoardThe MCR IQ™ Motor Control Board Series from Theia Technologies facilitates operation of motorized lenses, allowing users to control zoom, focus, P-iris, and optional IR filters.
