Gen3 image intensifier tube（GaAs）FOM1800+
GEN3 Image intensifier tube GaAs
Compared with the Gen2+ image intensifier tube, the Gen3 image intensifier tube uses GaAs photocathode. GaAs is more efficient in converting photons into electrons, can provide better resolution and sensitivity, and can provide better observation effects in darker environments.
