What is the difference between an infrared thermal imager lens and a camera lens
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
