Image intensifier tubes ECHO
The ECHO technology is the commercial grade image intensifier tube by Photonis, offering three high performance levels: the ECHO+, the ECHO and the ECHO14.
Although the ECHO+ offers a better FOM, the ECHO tube is ideal for those who want quality night vision at a reasonable price. The ECHO range of image intensifier tubes serve many night vision applications and make them perfect for sport shooters, hunters, airsoft practioners and night vision enthusiasts.

Description
ECHO image intensifiers are a high-performance, low-cost offering to the commercial market. This technology can offer ultra-fast Auto-Gating, a small halo and the high resolution expected from a high-grade tube.
Echo tubes are available in two high performance grades in both green or white phosphor offering the best option for any user.
Phosphor & Format available
P43 (green phosphor) or P45 (white phosphor)
The phosphor screen of the IIT converts the electron avalanche from the microchannel plate back into photons, resulting in the green image that has become the signature view in night vision technology.
Photonis was the 1st manufacturer in the world to develop and sell white phosphor Image Intensifier Tubes (IIT)
White phosphor, or P45, provides excellent recognition and has similar decay time properties as the P43 (green) phosphor. In night vision, white phosphor IIT comes from the aviation and special operations world. While there are no « lab » performance differences between P43 & P45, the choice of phosphor remains an operator’s preference.
During trials of soldiers performance under green and white phosphor night vision, no combat effectiveness difference was found. That’s why phosphor color is often a personal preference, the most important criteria being for the operator to have as less eye fatigue as possible.
16 mm Image Intensifier Tube
Photonis is the 1st and sole manufacturer in the world to develop a 16mm format intensifier tube. This new standard has enabled the design of modern, lighter and smaller night vision binoculars.
Reducing the load on a soldier is a constant challenge. We can notice a real evolution concerning the size and weight of our image intensifier tubes. We talk about SWaP: Size Weight and Power.
Reduction of SWaP contributes to enhance the efficiency and effectiveness of armed forces. Night vision devices that are designed around the 16mm IIT offer the tremendous advantage of having the same level of performance as those based upon the 18 mm intensifier tube, but with significantly reduced weight.
