H11706-40 current type (high quantum efficiency) PMTs

The H11706-40 photosensor module contains a metal-encapsulated photomultiplier, a high-voltage power supply circuit, and a gate circuit. The gate circuit protects the photomultiplier from excessive incident light, such as excitation light from a sample.The H11706-40 has a GaAsP photocathode surface for high sensitivity in the visible region.The H11706-40 also includes a high gain and low dark counting "P-Type" for photon counting applications.The H11706-40 has a GaAsP photocathode surface for high sensitivity in the visible region.The H11706-40 has a GaAsP photocathode surface for high sensitivity in the visible region.
