Compact Head-on PMT
Photon Counting Head H7828 Series
The H7828 series are photon counting head devices using a 19 mm (3/4") di-
ameter head-on photomultiplier tube, high-speed photon counting circuit, and
high-voltage power supply circuit. The high voltage supply for photomultiplier
tube and the discrimination level are preset to optimum levels, allowing photon
counting measurement by just connecting a +5 V supply. Despite its compact
size, the effective photosensitive area is as large as 15 mm in diameter, so the
incident light can be collected very efficiently. Compared to other PMT mod-
ules, the H7828 series devices have higher resistance to vibration and shock,
making them suitable for portable or mobile measurement equipment. Two
types of photomultiplier tubes with different spectral response characteristics
are provided for measurement in the visible range or visible to near IR range.
