what is exir night vision?

EXIR stands for EXtended InfraRed. The technology uses lights in order for the camera to see at night.

A night sight is, in most cases, a replacement sight that glows in low light so you can aim better. There are two different types of night sights. Fiber optic a colored piece of glass that use what light is available to illuminate.

There are numerous night maps in Modern Warfare. There is Gun Runner (Night), Hackney Yard (Night), Rammaza (Night), and Azhir Cave (Night). All of these maps require that you use night vision goggles if you want to see anything at all.

An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings. It does this by either emitting or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.

Photoreceptors for night vision are called rods. Rods can act as light detectors even in extremely low levels of illumination but are ineffective—they are known to "saturate"—in bright light. ... Both cones and rods participate in dark adaptation, slowly increasing their sensitivity to light in a dim environment.

An infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. ... An IR emitter generates infrared light that transmits information and commands from one device to another. Typically one device receives the signal then passes the infrared (IR) signal through the emitter to another device.

Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.

An infrared receiver, or IR receiver, is hardware that sends information from an infrared remote control to another device by receiving and decoding signals. In general, the receiver outputs a code to uniquely identify the infrared signal that it receives.

Day-Night and IR Surveillance Cameras. ... The camera can be a true day/night (TDN) with a mechanical IR cut filter (ICR), digital day/night, which adjusts electronically without a filter, or it can have IR LEDs (light-emitting diodes). Some cameras have IR LEDs surrounding the lens to provide illumination.

Visible light has a wavelength that ranges from 380 nm – 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm – 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with special equipment like a security camera.

Generation 2 night vision devices display a clean and bright image with good resolution, while providing a useful range of ~200 yards depending on the model.

Iwach is that the tinted or polarized lenses used on so-called night vision glasses are designed to limit or reduce the amount of light getting to the eye.

Some of this light may be infrared light that people can't see. Night vision goggles using image enhancement technology collect all the available light. Then, they amplify it so that you can easily see what's going on in the dark. The other night vision technology is called thermal imaging.

The infrared has longer wavelengths (700 nm to 1 mm) than those of visible lights (390 nm to 700 nm). Note though that visible light is the only radiation that can be seen by the human eye. The ultraviolet is much more intense and has a shorter wavelength (400 nm to 10 nm) compared to visible light.
