Image intensifier tubes:
Device is supplied with Photonis ECHO or 4G green and white phosphor image intensifier tube.
The Photonis ECHO technology is the commercial grade image intensifier tube by Photonis, offering two high performance grades to the commercial market for civilian users. ECHO image intensifier tubes serve many night vision applications for users that require good range and details at night and making them perfect for sport shooters, hunters, airsoft practioners and night vision enthusiasts. The ECHO14’s with UCD 14mm provide an image with a FOV of 36° compared to standard 40°.
The 4G Image Intensifier Tube (IIT) is a more affordable version than 4G+ while maintaining a high level of performance. 4G IIT provides operators high image quality and long detection ranges in the most challenging light conditions: brightness of equipment, longevity of intensifier tubes, ability to see farther in increasingly low levels of darkness and very fast auto-gating.
The Photonis 4G+ image intensifier tubes meet the stringent requirements of modern warfare at night to deliver end-users a very high performance in all field conditions. The 4G+ technology offers extended bandwidth for high image quality on all theatres of operation, a very fast auto-gating and a small halo providing more details around light sources. Thanks to a very high Figure Of Merit (FOM) and extended sensitivity, operators benefit from the best possible range in all types of environment.
