The H11461 series photosensor modules consist of a 28-mm (1-1/8") diameter side-on photomultiplier tube and a high-voltage power supply. These sideon photomultiplier tubes have long been used for spectroscopic applications and provide high gain and high sensitivity. Six types of photomultiplier tubes are provided as standard lineups to meet various needs for spectral response range. The H11461P-01 and H11461P-11 are selected as low dark count types ideal for photon counting and low-light-level measurement.
