![]() As seen in the images below, by activating your IR searchlight you will immediately give your position away to any enemy players who are using an image intensifier. While IR searchlights obviously make seeing targets a lot easier in poor conditions their use does have a major drawback: any other players using image intensifiers can also see the light from your searchlight. The effect of an IR searchlight can be seen in the image to the right. If you are looking through an image intensifier then the area where the light is pointing will be brightly illuminated. When activated an IR search not be visible unless you are looking through an image intensifier. However, as image intensifiers use light from the infrared spectrum and convert it to visible light, so IR searchlights can be seen through image intensifiers. Infrared (IR) searchlights are like regular searchlights, but they emit light on the infrared spectrum instead of the visible light spectrum this means that the light they produce cannot normally be seen. In addition to image intensifiers, some tanks are fitted with Infrared searchlights. The effect of turning on an IR searchlight on visibility Notice how the distant tank is slightly clearer and the barrel is visible with the higher resolution image intensifier.Ĭlick on an image to open it in full screen and get a better view ![]() The image intensifiers on tanks in-game typically have a resolution of 800 x 600 or 1600 x 1200, the difference between these resolutions is minimal and is often only noticeable when looking at long-range targets.īelow is an example of looking at a T-80U, located approximately 1.25 km away from the player, using an 800 x 600 intensifier and a 1600 x 1200 intensifier (all other stats are equal). The higher the resolution that an image intensifier is capable of outputting, the clearer the final image will be. While individually some of these elements may have only a small impact on image quality, newer image intensifiers will have improvements to most or all of them, providing much better image quality.ĭifferent image intensifiers are capable of producing images at different resolutions. There are a number of characteristics which affect the performance of image intensifiers, these are the resolution, the light multiplication factor, and the susceptibility to noise. Image intensifiers can only be used a night. Image intensifiers suffer from noise interference this appears as a form of TV static over the screen it is quite noticeable on early image intensifiers however more advanced systems (generally found on newer tanks) are less susceptible and the effect is much less noticeable, leading to them proving much clearer images. When image intensifiers are activated the screen picks up a green hue and you are generally able to see much further. These devices work by amplifying the light which enters the sensor, as well as converting some light from the infrared spectrum into visible light. The most basic type of night vision device is an image intensifier. Images in this article were created at night with the weather set to "Blind" so represent the operation of Night Vision devices under worst-case conditions (or close to it). Toggles the thermal sight between White Hot and Black Hot modes ![]() ![]() Toggles between standard view and image intensifier / thermal viewĬhanging the colour scheme of the thermal sight They can only be used from their designated views, for example, the tank commander's night vision system can only be used in binoculars, the driver's night vision is only used from driver seat or third person view and gunner view is only used from sniper seat. Tanks and helicopters can have different night vision devices for different crew members, for example, the gunners' sight may have a thermal imager, while the commander's (or in the case of helicopters the pilot's) view may have image intensifiers, and the driver's view a less powerful image intensifier. In addition, some tanks have the option to upgrade their image intensifier to a thermal imager, by unlocking a second modification (on some tanks the thermal imager is included with the original modification). Night vision devices are usually unlocked as tier 3 - 4 modifications, however, some tanks or helicopters have them access to them at tier 1 - 2. In addition infrared (IR) searchlights were added to tanks which historically had them. ![]() Two types of night vision devices were added, image intensifiers and thermal imaging systems. These devices provide a significant advantage in the now more common night battles. Update 1.91 "Night Vision" added Night Vision Devices (NVDs) to a number of high tier tanks and helicopters.
