LNVG-M

The LNVG (Light Night Vision Gear) is a modular NVG series designed by Radio Active. The goal was to make NVG more accessible and affordable.

Theres is currently a Series of monoculars and a binocular aviable.

The LNVG-M MK2 monocular has been published on thingiverse and the manual/ build instructions on google docs.

History

Monoculars

MK0 was a proof of concept and the lightest of all versions. It used, like all versions, C-mount lenses as an objective, but they were fixed with a 3D printed thread which proved hard to print right.

The next iteration the MK1 replaced the 3D printed C-count thread with an Aluminum insert, improved the stiffness and was the basis for the 1st Binocular versions

The ,as of writing, current version MK2 imprióved further the stiffness and introduced 2 sling loops and the capability to purce the housing. Also its the 1st generation which is able to collimate via tilting the Eyepiece and has the option of using a brass thread insert for mounting a J arm. It's also the Version the current 3rd Binocular housing design is based on.

Binoculars

First prototype was a hinged design like an AN/PVS-31. It was never fully built because of the inherent problems with collimation on hinged designs.

The 2nd prototype used a sliding mechanism for setting the IPD, thus eliminating any problems with the collimation, but had height problems. Only 1 one build.

Both prototypes are based on the MK1 Monocular design and have a lot of interchangeability of parts to the monocular design.

MK0 is the final prototype; here was the goal to make the unit flatter. This was achieved by placing the Gain knop and the battery compartment instead of the previous over - under design of the other 2 Prototypes.

Features

Monocular

• Lightweight (compared to AN/PVS-14 and clones)- it can weight under 290g (including tube and battery)
• Modular
• Opensource (under cc by-nc-sa)
• Man gain version available
• Fits on normal AN/PVS-14 J arms
• Uses a single CR123 Battery (up to 24 h runtime)
• Free colimionation on both axxis
• Rainproof

Binocular

• Gain and on off combined
• Battery compartment is additionally locked while unit is on
• Sliding IPD adjustment
• Individual pod flip up with automatic shutdown
• Uses 1 CR123 Battery and can be powered by a external powerpack
• Powerpack with integrated counterweight.
• base of the monocular- replacement of only 1 component needed for conversion
