1. What is the function of auto-gating Gen . 3 night vision?

Gen.3 devices feature a micro-channel plate like the Gen. 2 devices, but the photocathode is made of gallium arsenide (GaAs).

Autogating is an important new feature that dynamically controls the amount of current that’s fed into the image intensifier. By quickly oscillating - or autogating – current draw by the microchannel plate eliminates the potential for damage due to bright light.

And in addition to keeping your equipment safe, autogating significantly increases operator safety as well. By instantly adjusting to changing light conditions, autogating ensures that high risk room-to-room searches in urban environments can be conducted with complete confidence, with no risk of losing situational awareness in the event of a sudden flash or burst of bright light.

2. What is another advantage of Gen.3 ?

Gain and resolution are further improved compared to Gen. 2 and Gen. 2+ tubes, and the microchannel plate is coated with an ion-barrier to improve tube life. Lately, manufacturers started to produce also devices where the ion-barrier is removed – called filmless tube versions. In such devices, the resolution is further improved, and there is less ˝halo effect˝ around bright lights. Also the sensitivity （up to 2200） and signal-to-noise ratio （up to 36） is improved.

3. For the Gen. 3 night vision devices also P43 white-phosphor/P45 green-phosphor cathodes are available, for a black and white image. The resolution with this tube is further improved, and longer time observation is more comfortable.

Be sure you don't expose the 2nd Generation,3rd generation analog night vision devices to sunlight because it can damage the image-intensifier tube!
