GStabilized Light Sources For PMT L11494 Series
The majority of these devices are LED light sources that have been
developed for visual-sensitive compensation of PMTs and PMT
modules.
Because the amount of light generated by the LED is monitored and
controlled by a photodiode, these devices always generate stable light
of approximately 1 pW.
