Side-on PMT Photosensor Modules H11461 Series 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. Product Variations Type No. H11461-01 H11461-02 H11461-03 H11461P-01 H11461P-11 H11461-09 Spectral Response 185 nm to 710 nm 185 nm to 900 nm 185 nm to 900 nm 185 nm to 710 nm 185 nm to 850 nm 160 nm to 320 nm* Features Low noise in UV to visible range For UV to near IR range High sensitivity in UV to near IR range For photon counting in UV to visible range For photon counting in UV to near IR range For UV range, Cs-Te photocathode This product can't be used at vacuum environment or reduced pressure environment. Please pay attention when the H11461 series is used for measuring the light below 190 nm. Specifications (at +25 °C) Parameter Anode Cathode Suffix Input Voltage Max. Input Voltage Max.
