Request InfoHamamatsu CorporationHamamatsu Photonics K.K.’s Electron Tube Div. has released a photomultiplier tube with enhanced UV sensitivity. The R11540 is a 28-mm-diameter side-on device with a spectral response ranging from 185 to 760 nm. It produces 40% quantum efficiency at 350 nm and anode sensitivity of 11.3 x 105 A/W at 350 nm and 12 x 105 A/W at 420 nm. Its sensitivity and high gain of 1 x 107, typical, make it suitable for low-light detection of UV and visible light in fluorescence spectrometers. It also can be used as a fluorescence detector for high-performance liquid chromatography, as a sulfur dioxide...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueBandpass FiltersThe ADVANTECH™ hard coat bandpass filters from Andover Corp. offer steep slopes, high light transmission, durability, and long life for demanding applications.
