Request InfoHamamatsu CorporationHamamatsu Corp.’s ORCA-Flash2.8, a high-sensitivity digital camera based on the FL-280 scientific CMOS image sensor, is designed for low-light imaging at high frame rates. The FL-280 features 2.8 megapixels and a pixel size of 3.63 x 3.63 μm. Its wavelength sensitivity ranges from the UV to the visible, with peak sensitivity at ~450 to 500 nm and with >60% quantum efficiency. Typical readout noise is 3 e— rms, even at fast readout speeds. Producing low dark current, it requires cooling to only 5 °C. The camera’s readout speed ranges from 45 fps at full resolution...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2022 IssuePhoton-Counting Sensor and CameraGigajot Technology Inc.’s QIS41 camera, built around the GJ04122 sensor, pairs well with standard 4/3-in. microscopy optics, bringing high resolution and low-light performance to scientific and...Photonics Spectra February 2024 IssueCMOS Image SensorsThe Emerald™ Gen2 line from Teledyne e2v is a CMOS image sensor family developed for machine vision, outdoor surveillance, and traffic detection and monitoring cameras.
