PNG-MT Thermal Goggles

Over the many years of our experience in the design, development and manufacture of night vision devices we have worked closely with British, other NATO and non-NATO Armed Forces, Special Forces and Police Special Forces in order to produce the products and features required for today's and tomorrow's threat situations.

The PNG-MT goggle range is the result of such close cooperation's and is a state of the art world beating product which is complemented by a wide range of specially developed accessories enabling the user to perform a huge variety of missions based on just one sensor platform --- PNG-MT. Designed, developed and manufactured in Britain to ISO 9001 quality levels the PNG-MT is the world's smallest and lightest thermal imaging goggle.

It uses an advanced glass reinforced polymer main body with a centre of mass as far to the rear as possible to minimise neck strain during prolonged head and helmet worn operations. Two Lithium "AA" batteries, for light weight, give up to 7 hour's continuous operation. High quality germanium optics are used for maximum image quality and the entire monocular body, electronics and optics (5.8 to 25mm) are filled with dry nitrogen for ultimate reliability in all missions.

The unique Near Eye LED display always produces a large crisp image right in front of the eye and overcomes the "tunnel vision" problem common in inferior designs. This gives an image having an apparent angle of view of 40° horizontally, which is similar to that of the human eye and therefore considerably aids speed and clarity of target acquisition. When head/helmet worn in the 5.8mm lens option model the image is seen by the user is close to a 1:1 ratio to actual size therefore considerably enhancing judgements of distance and safety of manoeuvre. The PNG-T range comprises four models in focal lengths from 5.8 to 25mm for head/helmet and hand held applications and two models in 75 and 150mm focal lengths for hand held and tripod mounted surveillance giving detection ranges up to 1.5 and 3 km for human sized targets.

Useable hand held, helmet mounted, head mounted or tripod mounted, the PNG-MT range does everything. And this includes optional anti-mist filters and adaptors for attaching instantly to camcorders, SLR cameras and CCTV cameras for total darkness surveillance. You can even power the PNG-MT directly from a vehicle cigarette lighter socket or any 12v supply and take the live PAL video directly to any compatible recording device or transmitter.

For security and convenience the PNG-MT goggle auto switches off when flipped up and auto switches on with no switch resetting needed when flipped back down again. Shuttered rubber eyecups are also available which simply screw on without needing to remove the normal soft fold-back eyecup. For added security an icon inside the 27mm eye relief eyepiece illuminates to warn against a low battery charge situation. And of course all accessories can be used with no tools required for attachment, adjustment or operation.
