Request InfoHamamatsu CorporationBRIDGEWATER, N.J., Feb. 18, 2014 — Hamamatsu Corp. has added red-sensitive detectors to its ultracompact micro photomultiplier tube (PMT) line, suitable for integration into portable or compact instruments in point-of-care testing, security applications and environmental monitoring. The new products have a spectral response range from 300 to 850 nm, with high quantum efficiency values in the red and near-IR regions. They join the company’s existing UV/visible micro PMTs, which offer spectral sensitivity of 300 to 650 nm. All models feature a photosensitive area of 3 × 1 mm, low dark current, high gain and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/13/2023FMCW Lidar Vision SystemsThe Eyeonic™ Vision System Portfolio from SiLC Technologies are vision detection systems that utilize FMCW lidar technology and can identify objects beyond a kilometer away while also providing...Vision Spectra Spring 2024 Issue6-MP SWIR SensorsThe Acuros®6 and the Acuros®4 CQD® from SWIR Vision Systems are SWIR image sensors for defense, scientific, automotive, and industrial vision markets.
