An image intensifier boosts the intensity of the incoming light. By converting photons to electrons and back to photons, the light intensity can be increased significantly. Scroll down for more information about how this works.
Another feature of an image intensifier is that it can act as an ultra-fast shutter. The photocathode can be switched between on and off in a matter of nanoseconds.
The photocathode converts incoming photons to electrons. Several photocathode materials are available, each with a different spectral sensitivity and quantum efficiency.
In the micro-channels, the electrons are multiplied to increase light intensity at the output of the intensifier. The multiplication gain can be set in our software.
The phosphor screen converts electrons to photons. There are several types of phosphor available, each with a different decay time and conversion efficiency.
