G O/E converter
G Low-light-level detection
G Portable high-sensitivity
light detector
The H8443 is a photomultiplier tube (PMT) module consisting
of a 25 mm (1 ") head-on PMT and a low power consumption
high-voltage power supply, integrated into a compact case.
The H8443 operates on a low voltage supply (+ 11.5 V to
+ 15.5 V) and offers high sensitivity, wide dynamic range and
high-speed response, which are superior to conventional light
sensors.
