  The thermal imaging effect focuses on the movement, and the choice of fixed focus and zoom thermal imaging depends on the specific project requirements. The difference between fixed focus and zoom thermal imaging: 1. The price difference is huge. For example, the price difference between 100mm fixed focus and 20-100mm zoom thermal imaging is nearly doubled. The price difference is so big, mainly because the zoom thermal imaging process is complicated, and multiple controllable lens groups need to be built in the zoom lens. 2. Performance difference. At a focal length of 100mm, the imaging effects of the two are the same. However, when looking at a close target within a range of 10 meters, due to the long focal length of the fixed-focus lens, the image of the close target is too large, but the whole thing cannot be seen. For example, when you see a person, you can only see part of the body. The zoom can be changed to 20mm focal length, and multiple targets can be seen within 10 meters

 What is the difference between an infrared thermal imager lens and a camera lens 1. Thermal camera lens Infrared camera lenses are usually made of germanium glass. The glass 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 infrared camera lens is compared with the ordinary germanium lens used in the ordinary camera lens. The reserves are not low, but the extraction of high-concentration germanium is very difficult, so the production cost of germanium lenses is relatively high, and the market price is often higher than that of ordinary camera lenses. 2. camera lens The lens of an ordinary camera is usually made of optical glass, and its most specialized function is of course to refract light (usually called magnifying objects). Generally, optical glass is artificially synthesized. Ordinary cameras/camcorders underexpose infrared rays, the
