Explanation: 

•

 

Off

: MCP gating is disabled, 

Intensifier Voltage

 is continously 

on; there is no contribution of the MCP to the overall extinction 
ratio. Maximum fps can only be achieved with MCP gating 

Off

 

•

 

On:

  MCP gating is enabled; MCP 

Intensifier Voltage

  is 

switched off after the end of the photocathode exposure and 
reactivated immediately after the sCMOS sensor readout is 
done. With this setting, the MCP additionally contributes to the 
overall extinction ratio. Reactivation of the 

Intensifier Voltage

 

takes an extra 4 ms; this mode slows down the maximum 
achievable framerate.
