PVS-14 NNVT Gen 3 Green Phosphor Monocular - FOM 1600
A PVS-14-pattern analogue night vision monocular built around an ARGUS PVS-14 housing and fitted with an NNVT Gen 3 green phosphor image intensifier tube. The supplied tube sheet records 60 lp/mm resolution and a signal-to-noise ratio of 26.2, giving a calculated FOM of 1572 and a rounded specification of approximately 1600 FOM. The tube is autogated, includes automatic brightness control and is supplied with factory QC documentation.
Gen 3 GaAs photocathode technology
The fitted NNVT Gen 3 image intensifiers use gallium arsenide (GaAs) photocathodes. This is a different photocathode technology from the multialkali designs commonly associated with Gen 2 and Gen 2+ tubes. The photocathode converts incoming light into electrons before amplification in the microchannel plate.
Gen 3 describes the tube technology; green or white phosphor describes the colour of the output screen. Similar FOM values do not make Gen 2+ and Gen 3 tubes technologically identical: FOM combines resolution and signal-to-noise ratio, but does not describe photocathode material or full spectral response. Actual image performance also depends on the individual tube specifications, optics and lighting conditions.
