The thermal image sight is the sight that converts the target thermal radiation image into the visible light image. A kind of passive infrared sight.

The thermal image sight can distinguish the slight difference in thermal radiation between the target and the background. It can be found and aimed at the target day and night. It can also find the target through clouds and some camouflage.

Definition of thermal imaging


All objects in nature, whether arctic glaciers, flames, human bodies, or even the extremely cold deep space of the universe, will have infrared radiation as long as their temperature is higher than absolute zero - 273 ℃, which is the result of the thermal movement of molecules inside the object. Its radiation energy is proportional to the fourth power of its own temperature, and the radiation wavelength is inversely proportional to its temperature. Infrared imaging technology is based on the level of radiation energy of the detected object. The thermal image transformed into the target object after system processing is displayed in gray-scale or pseudo-color, that is, the temperature distribution of the measured object is obtained to judge the state of the object. Therefore, detecting the heat emitted by objects is the inherent gene of infrared thermal imaging technology.

Thermal imaging is a detection device that detects infrared energy (heat) through non-contact detection and converts it into electrical signals, and then generates thermal images and temperature values on the display, and can calculate the temperature values.

Thermal imaging is also called long-wave infrared imaging. Passive infrared imaging with a working band of 3-14 microns. It is mainly used to record the infrared radiation of the object when it is heated. It can change the thermal image of the scene radiation into a visible two-dimensional image. Thermal imaging systems mainly include thermal radiation electronic imaging and thermal photography.

Virtual external image thermal imaging technology formed by human thermal radiation is also known as infrared radiation imaging technology. According to the optical theory of natural object imaging, any object that can be captured by light can generate a photosensitive imaging state of the background object. In modern society with highly developed science and technology, nightscape photography additional device with infrared thermal imaging has been widely used. The infrared imaging principle, is mainly based on the infrared radiation principle that the object is higher than the absolute temperature of space - 273.15 degrees. That is to say, all objects that are higher than the absolute temperature of space will form a thermal infrared radiation state, while objects that are lower than the absolute temperature of space - 273.15 degrees do not have thermal infrared radiation.


Application fields of thermal imaging sight


The thermal imaging sight is applicable to the armed police, anti-terrorism, special police rescue, sniping scene, major arrest operations, anti-drug and anti-smuggling, border stability maintenance, national defense and border defense, special operations, actual combat exercises, field reconnaissance, all-black patrol, and jungle search and rescue.


The company's main products include infrared lenses, night vision objectives lens and other customizable optical lenses. It is mainly suitable for scenarios such as thermal imagers, infrared sights, night vision, infrared cameras, and drone monitors.
