Gen 2 Night Vision
Gen 2 night vision is a big step up in the performance of Image
intensifier devices. Much of
the distortion found on the edges of the
gen 1 night vision has been reduced or eliminated.
Gen 2 night vision
devices provide a useful image through out the full field of view.
These devices provide a much brighter and higher resolution image under
lower light conditions.
The deference between Gen 1 night vision and
Gen 2 night vision was brought about by the addition of the
micro-channel plate. The number of electrons produced by the
intensifiers photo cathode are multiplied thousands of times and better
aimed at the phosphor screen.
Generation 2 nvds are smaller and lighter. They require a smaller
charge to drive the electrons into the phosphor screen so battery usage
Gen 2 devices produce a very good image under a quarter moon, distant
urban lighting and the glowing clouds of a distant city.
The intensifier tubes used in
gen 2 nvds have some variations in
quality and performance. Just like the gen 1 intensifiers, improvements
in the manufacturing process over recent years are showing up in the
