Description
Photonis 4G technology is perfectly suited to the stringent requirements of night combat operations by providing operators high image quality and long detection ranges in the most challenging lighting conditions. Indeed, Photonis 4G bandwidth is twice larger than Gen III image intensifiers, collecting more photons in all operational conditions, and providing soldiers
with the crucial tactical advantage of seeing 1100nm lasers target designator that no other image intensifier can detect. With the broader availability of night vision devices, the challenge is to have the best performance image intensifier based equipment that is always more efficient than the one of the opposing force.
Option available
P43 or P45 |
|---|
P43 (green phosphor) or P45 (white phosphor)
A phosphor screen does not affect the performance of the image intensifier tube, and therefore one phosphor is not better than another. Phosphor selection is often a personal preference. P45 is a black and white phosphor which provides excellent recognition. P45 has similar decay properties as the P43 (green) phosphor, but gives the user with B&W images which are more easily recognized by the human eye by providing more discriminating shades of intensity. The result is less eye fatigue and faster recognition, particularly in sandy or rocky terrain.
16 mm |
|---|
16 mm Image Intensifier Tube
Photonis was the first manufacturer to develop white phosphor image intensifier tubes and is also the only company to offer a 16mm format tube. Thanks to its strong capacity for innovation, Photonis encourages night vision equipment manufacturers to develop their own equipment. Indeed, by introducing the 16mm tube, Photonis has allowed the design of new night vision binoculars, lighter and less voluminous while still being more efficient.
