History of Night Vision

Eagle30 night vision devices are most affordable, but rely on ambient light to function properly. They use an S20 photocathode that provides about 1000x light amplification.

Image resolution and light amplification are improved in the Eagle40 night vision devices. Utilizing a microchannel plate (MCP) and an improved image intensifier tube, coupled with an S25 photocathode, you get better brightness than first generation night vision.

Eagle70CC night vision is a step up from second generation in that the new photocathode is used. A microchannel plate (MCP) is still present and the new coating on the MCP increases tube life. An ion barrier film on the microchannel plate causes a halo effect when looking at bright light sources. Generation 3 night vision devices and rifle scopes consume more power, but have light amplification of 30K-50K.

Eagle70CC night vision devices differ from Eagle40 generation in the use of auto-gated technology and use of a thinner ion barrier on the microchannel plate (MCP). Automatic gating regulates the photocathode voltage, which makes the night vision device to automatically adjust to changes in light conditions. The thinned layer of the ion barrier improves image noise and luminous sensitivity. However, a thinner or removed ion barrier also decreases the life of the intensifier tube from 20,000 mean time to failure to 15,000 hours. Generally NV devices are replaced before reaching this point.
