Request InfoHamamatsu CorporationHamamatsu Corp. has introduced a hemispherical acrylic lens designed to increase anode sensitivity and relative output in the company's 11/8-in. photomultiplier tubes. Attaching the lens to the entrance window of side-on PMTs widens the capture area by a factor of 3, increasing the amount of incident light reaching the photocathodes. Improvement in X and Y axes occurs at wavelengths above 300 nm.See full productRelated content from Photonics MediaPRODUCTSVision Spectra Winter 2023 IssueCompact IR Zoom LensThe Ophir® FoldIR 30 - 450 mm f/3.4 continuous zoom lens from MKS Instruments Inc. is a long-range, compact folded optics IR zoom lens for gimbal systems and payloads in air-land-sea...Photonics Spectra November 2022 IssueIndustrial Microscope ObjectivesMXPLFLN series industrial microscopy objectives from Evident Scientific combine a high numerical aperture and long working distance for flexibility in various inspection applications.
