Side-on PMT
Photosensor Modules H11461 Series
The H11461 series photosensor modules consist of a 28-mm (1-1/8") diame-
ter side-on photomultiplier tube and a high-voltage power supply. These side-
on 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.
