The difference between infrared camera lens and ordinary camera lens

Many people now have a camera, and often take the camera to travel and take pictures. Some people think that the infrared thermal imaging lens and the camera lens are the same, and they don't see that there is a big difference between the two. So from a professional point of view, is the thermal imaging camera lens the same as the normal camera lens? This is a question worthy of in-depth discussion. Let’s take a closer look at the difference between thermal imaging camera lens and normal camera lens. The difference between infrared camera lens and ordinary camera lens: 1. The price is different: Infrared lenses are much more expensive than ordinary optical lenses, mainly because of the different lens materials. 2. The lens is made differently: Infrared camera lenses are usually made of germanium glass, which has a high refractive index. It is only transparent to infrared light, but opaque to visible light and ultraviolet light, so it can be divided into plants and animals in a very dark environment. The lens of an ordinary camera is usually made of optical glass, and its most lized function is of course to refract light (usually called magnifying objects). 3. Different uses: In the ordinary surveillance environment, infrared imaging is not required, but a normal lens is used; in the infrared thermal imaging surveillance environment, an infrared lens must be used. From the above introduction, it can be seen that the two are not the same thing. The infrared thermal imaging lens has more functions than the camera lens. It can provide more image information than the camera lens, such as image temperature information, sound, visible light image information, and so on. These are the functions that the camera lens cannot have.
