Stabilized light sources for PMT
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. It contains a photodiode to monitor and control the LED emission intensity so that they constantly output stable light of approximately 1 pW.
|Peak emission wavelength||465||522||555||592||nm|
|Spectral half width||26||35||30||18||nm|
|Light emission power||1 ± 0.5 *1||pW|
|Emission stability (0 °C to +50 °C)||±2 Max.||%|
|Battery||Button battery SR41 or equivalent||-|
|Battery service life||Min.||24||h|
|Operating ambient temperature / humidity *2||0 °C to +50 °C / below 85 %||-|
|Storage temperature / humidity *2||-20 °C to +60 °C / below 85 %||-|
*1 Adjusted by using a 22 mm effective diameter photon counting head placed at a position 5 mm away from the L11416.
*2 No condensation
