Metal Package PMT with Gate Function
Photosensor Modules H11526 Series
The H11526 series is a photosensor module that allows gate operation. The
combination of built-in metal package PMT and gate circuit makes this mod-
ule compact yet still provides excellent characteristics: 100 ns minimum gate
width, 10 kHz repetition rate. This module also contains a high-voltage power
supply so that PMT gain can be varied by simply adjusting the control vol-
tage. The internal protection monitor issues an error signal if high-intensity
light enters the module.
