About Night Vision Goggles

Night Vision Goggles, also referred to as night vision devices, are designed to allow the user to maintain their vision in environments with very low light. Typically used by police forces or the military, civilian users have often found innovative uses for the devices, such as maintenance work and hunting. The name is used to refer to the complete unit, which is likely to include a mounting system for an image intensifier tube and a protective housing, as well as the physical ?goggles? themselves. It is possible to purchase additional accessories in order to add functionality, such as infra-red illuminators and telescopic lenses, though fitting will depend on the respective model?s compatibility with these accessories. All night vision devices available in the UK are designed to work with commercially available batteries. This means that purchasing replacements should not be difficult, though depending on the model, the amount of usage you get from a single set of batteries will vary. Designed to tolerate a large amount of physical activity and inclement weather, many goggles can withstand a great deal of wet weather and rough usage, though it is important to remember that the technology contained within is advanced and should be treated with respect. Night vision devices were first invented during World War II, though reached prominence and notoriety thanks to their usage in the Vietnam War. Since the first experimental devices were constructed, their technology has advanced considerably. This has led to a classification of ?generations? of night vision goggles, of which there are five. The classification system reflects both features and image quality, with advancing technologies bringing new possibilities to the devices. While American manufacturers abide by the system, their European counterparts do not.
