Kaelor KPNVG-18 Quad-Tube Panoramic Night Vision

The Kaelor KPNVG-18 is an independent commercial quad-tube panoramic night vision device built around Kaelor Works' own housing platform and LEN panoramic optical package. It is not manufactured by ARGUS or L3Harris.

Four 18 mm image intensifier tubes form the panoramic image. The two central channels provide the forward binocular view, while the two outer channels extend peripheral coverage. The result is an approximately 97-degree horizontal by 40-degree vertical field of view at 1x magnification.

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

Tube configurations

• NNVT4 Gen 2+ green phosphor, FOM 1400
• NNVT5 Gen 2+ white phosphor, FOM 1600
• NNVT Gen 3 green phosphor, FOM 1800+
• NNVT Gen 3 white phosphor, FOM 1800+

FOM is calculated from tube resolution and signal-to-noise ratio; it is useful for comparing tube classes but does not describe every aspect of the viewed image. Individual tube data sheets are supplied with the completed device.

Higher-spec tube requests: FOM 2000+ tubes and other specific tube requirements may be available by request. Contact us before ordering to discuss sourcing, tube matching and current availability.
