ARGUS BNVD 1431 NNVT Gen 3 White Phosphor - FOM 1800

An ARGUS BNVD 1431 analogue binocular night vision device fitted with NNVT Gen 3 white phosphor tubes. This FOM 1800 configuration combines an articulating binocular housing with autogating and automatic brightness control.

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.

Tube data sheets and image references

The tube specification sheets shown in the gallery are reference examples for the photographed unit. Individual image intensifier tubes naturally vary in resolution, signal-to-noise ratio, gain and cosmetic characteristics, including between the left and right tubes. Refer to the sheets supplied with your unit for its individual measurements; not every device will reproduce the exact readings on the photographed sheets.

Through-tube photographs and videos are for reference. Camera exposure, white balance and ambient lighting can change recorded phosphor colour and brightness compared with direct viewing.

Complimentary lens protection

Sacrificial lens protectors are available free of charge on request and are not included by default. Select the complimentary lens-protector option above when ordering to add your request to the order. The gallery image is a reference photo; protector design and fitment vary by model. We will confirm suitable fitment for your model before dispatch.
