The term usually refers to a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, and some type of mounting system. NVDs are most often used by the military and law enforcement agencies, but are available to civilian users. The image produced is typically monochrome, e.g. The image may be a conversion to visible light of both visible light and near-infrared, while by convention detection of thermal infrared is denoted thermal imaging. ![]() Night vision device ( NVD), also known as a night optical/observation device ( NOD), is an optoelectronic device that allows images to be produced in levels of light approaching total darkness. To date, there have been four generations of image intensifier devices produced: Gen 0 through Gen 3. Image intensifier tube technology has evolved over the past 50 years through a series of “generations.” In order to differentiate night vision products and determine which is best for your application, you should understand the generations.Each generation (Gen) has been defined by specific technology advancements.
