These incredible night vision goggles are used by British armed forces and are now available to the civillian population for only £69!
The ultimate boys toy or night-time personal security aid, the uses to which these goggles can be put to is limitless. These infrared goggles allow you to see up to 15 meters in pitch black darkness!
Researchers at the University of Florida have created a nickle sized night imaging device that could one day be incorporated into smart phones. The device uses a different technology to that used by current military night vision goggles and the tech is so small and inexpensive that we could soon be talking about night vision glasses rather than goggles.
Night vision googles use a photocathode that converts invisible infrared light photons into electrons, which are accelerated under high voltage and driven onto a phosphorous screen, producing greenish images which are usually too dark to see well.
Because the whole process needs thousands of volts and a cathode ray vacuum tube made of thick glass, night vision googles are big.
To make the whole process smaller, the experimental imaging device instead replaces the vacuum tube with layers of organic semiconductor thin film material.
It works by using a photodetector connected in series with an LED and, when operated, infrared photons are converted into electrons and injected into the LED, which produces visible light.
The professor said that the technology could weigh a couple of ounces and be small enough to use in a mobile phone camera, and it will be cheap to manufacture because it uses the same equipment used to make laptop screens or TVs.

Insight Technology Inc. has landed a $34 million deal to develop and supply night vision goggles for the US army in Afghanistan. Under the deal, the company will develop goggles that utilise both of the major technologies involved in night vision glasses – thermal imaging and image intensification.
Night vision goggles play a critical role in the allied armies fight against the Taliban in Afghanistan.

Some people are sceptical as to how night vision goggles can actually work. How could such equipment enable you to see buildings, animals, and other people in the pitch black of a moonless night? Well, of course they do work, and are a vital piece of equipment for any modern soldier. Night vision goggles work through infra-red technology.
The upper end of the infrared spectrum is emitted as heat rather than reflected as light. Night vision goggles ’see’ this infra-red heat. Hotter objects such as human bodies and animals, give off quite a lot of infrared heat, therefore making them easily detectable by night vision goggles.
What can you expect to see with your pair of night vision goggles? The following video I found on YouTube gives you some idea of what kind of vision you can expect when looking through night vision goggles in the pitch black – note that the scenes recorded through the goggles in the video are not the identical Biritish Army night vision goggles advertised at this site and sold via MenKind, but they should give you an idea of what to expect.
