High detection efficiency
The H11123 is a photon counting head device consisting of a 28-mm (1-1/8")
diameter head-on photomultiplier tube, high-speed photon counting circuit,
and high-voltage power supply circuit. The high voltage power supply for pho-
tomultiplier tube and the discrimination level are preset to optimum values, al-
lowing photon counting measurement by just connecting a +5 V supply. The
H11123 can operate at high count rate.
The effective photosensitive area is as large as 25 mm in diameter, so the in-
cident light can be collected very efficiently.
