Glossary | Night vision devices | Performance | Generation | Other
Third-generation night vision devices deliver a much brighter and sharper image than the second generation. This is achieved by the additional use of photocathodes with additional chemical gallium arsenide. Noise is minimised and the lifetime of the devices is longer compared to the earlier generations.
Third-generation night vision devices are not available for purchase in Germany. This is mainly due to patent regulations and the fact that the US government prohibits the export of the devices.
But there are very good devices of the 2 ½ generation and the 2 super plus generation, which conform to the quality standard of the third generation. Image sharpness, brightness and noise are all comparable.
