Request InfoSunex Inc.Sunex Inc. has introduced IR-cutoff filters for use with CCD/CMOS color sensors to produce true color images. The precision-polished windows have a dielectric coating to block the transmission of IR radiation while passing the visible spectrum. Cosmetic surface quality specification is better than 20-10 scratch-dig after coating, and defects are <20 µm. Filter thickness is 1.0 mm, and standard size is 15 × 15 mm, with custom sizes available. Dimension tolerance is ±0.1 mm, and surface flatness is ≤3 fringes.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssueTime-of-Flight CameraThe DepthVista time of flight (ToF) camera from e-con Systems Inc. features a ToF depth sensor for depth measurement and the onsemi AR0234 color global shutter sensor for object identification. ...Photonics.com 4/24/2023Industrial and Embedded CamerasXIMEA's prototype models from the xiX-camera line are equipped with Sony’s Pregius™ sensors that easily replace former Sony CCD sensors.
