OVERVIEW
The L11416 and L11494 series are LED light sources
mainly designed for adjusting the sensitivity of PMT
(photomultiplier tubes) and PMT modules. The L11416
series is a test tube type easily mounted in lab devices
such as for blood sampling, while the L11494 series is a
plate type designed to be placed on a sample stage.
Stable continuous light of approximately 1 pW is always
output because the LED emission power is controlled by
monitoring with a photodiode.
