Photek’s range of photocathode gates units can be used with our image intensifiers and PMTs as ultra fast electronic shutters.
This technique is useful when the detector is used in high brightness situations or when capturing very fast moving objects. The gate unit operates by turning the photocathode on and off to 3 ns with a 300 KHz repetition rate (model dependant). For UHV detectors our GM-MCP gate module enables direct gating of the MCP to 8 ns. This is particularly useful when time slicing of electrons and ions is required.
