Kaelor KPNVG-18 Dovetail Quad-Tube Panoramic Night Vision

The Kaelor KPNVG-18 is a LAN18-platform quad-tube panoramic night vision goggle, also described as a panoramic NVG or pano NVG. Four 18 mm image intensifier tubes provide a central binocular view with extended peripheral coverage.

The four-tube panoramic layout provides an approximately 98 × 42-degree field of view at 1× magnification, with black or tan housing and the BNVIS dovetail mount interface.

Construction uses engineering polymer across the central bridge assembly, main body and optical pod housings.

Built to order - approximately 7 days before dispatch. This preparation period covers component sourcing, assembly, collimation, functional testing and order preparation. It is not a delivery estimate.

Gen 3 GaAs tube options

The NNVT Gen 3 options use gallium arsenide (GaAs) photocathodes, a different photocathode technology from the multialkali designs commonly associated with Gen 2 and Gen 2+ tubes. This GaAs specification applies to the Gen 3 configurations only, not to the NNVT4 or NNVT6L Gen 2+ options on this page.

Tube generation and phosphor colour are separate specifications. FOM combines resolution and signal-to-noise ratio, but does not describe photocathode material or full spectral response. The supplied tube configuration is the option selected when ordering; individual tube data and actual lighting conditions remain important.

Tube configurations

• NNVT4 GEN2+ green phosphor, FOM 1400.
