Photomultiplier tube module H16722P-50

The H16722 series are photomultiplier tube modules with an internal high-voltage power supply circuit and a cooler installed to the metal package photomultiplier tube having a GaAsP/GaAs photocathode. Efficient cooling was achieved by placing the cooler near the photomultiplier tube to reduce thermal noise emitted from the photocathode and a high S/N ratio can be obtained even at extremely low light levels. The H16722-50 series have sensitive along a wide spectral range from 380 nm to 900 nm. The photomultiplier tube is maintained at a constant temperature by monitoring the output from a thermistor installed near the photomultiplier and then regulating the current to the thermoelectric cooler.
