What are the different types of night vision optics?

There are many different types of night vision optics that can be used to help you see in low lighting. Different devices are usually categorized both by the type of device, with regard to how it is intended for use, and the type of technology it uses, often called generations. Among the common types of optics with different uses include binoculars, monocles, weapons and glasses. The differences in the technology used in night vision optics are usually referred to as generation, with at least a generation of one to four commercially available. These devices are often used by military and enforcement of law, as well as search and rescuers. Their use of a civilian can be limited in many countries, especially facilities intended for use with firearms such as night vision ranges. The first night vision of devices S, sometimes referred to as generation zero, was developed during World War II and used active infrared lights, although later versions used only passive amplificationPír.

One of the primary ways of categorizing the night vision optics is the intended use of the device. Such devices can often be found as a telescope and monocles designed for use in eye holding. This allows efficient night vision and newer devices even include close detectors that automatically turn on and off. The ranges of night vision that can be associated with weapons and other types of scope can often be found, although they can only be limited to military and enforcement of law in some areas. There are also optics of night vision that can be found as glasses, often worn with a strap around a person's head or associated with a helmet.

Night vision devices are also often categorized by technology used in such devices. Generation One devices are still commercially available, although the quality of the image of such devices is much smaller than the generation three and four permanagement. Later generations also usually include other features such as digital controls and automatic shutdowns that protect the user's vision automatically by off the device when exposed to bright lights. This is important because most night vision optics uses to function of light amplification, and therefore exposure to bright lights can potentially damage the user's vision.
