Request InfoLaser Components (UK) Ltd.CHELMSFORD, England, Sept. 20, 2010 — Laser Components UK Ltd.’s new Count single-photon counters achieve a quantum efficiency of >70% in the red region and, according to the company, a higher quantum efficiency in the blue spectral range than other modules on the market. They are suited for measurements across the wavelength range from 400 to 1000 nm. The devices are based on a purpose-developed silicon Geiger-mode avalanche photodiode and on quenching and signal-processing electronics from PicoQuant GmbH. Available in a compact housing, the photon counters can be easily integrated into user applications. ...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssueCollimated BacklightThe CSBACK collimated backlight from TPL Vision provides high-intensity illumination in a small package for inspection and measurement projects requiring precise silhouetting.
