The function of long wave infrared lens

IR lens (long wave infrared lens) has a very wide range of applications. It can be used for special purposes corresponding to infrared or as a normal lens. In other words, depending on the use occasion, the infrared corresponding lens can be used flexibly with conventional color cameras, black-and-white cameras, and day-night conversion cameras. The black-and-white camera does not have an infrared cut-off filter, but the spectrum of daylight also contains infrared light, so even in daylight conditions, the imaging of the black-and-white camera will be interfered by infrared rays. Therefore, the corresponding infrared lens can effectively improve the image quality. 1. The infrared light of the IR surveillance camera lens focus is consistent with the visible light, and the imaging is clearer. 2. The IR lens adopts the latest optical design and special optical glass material (LD optical glass) technology to eliminate the focal plane shift of visible light and near-infrared light. 3. IR lens (long wave infrared lens) adopts special ED lens to solve the "out-of-focus" problem of ordinary electric zoom lens under infrared light conditions. 4. The IR lens uses a special coating design and special optical materials so that the light in the 350-950nm band can be well corrected for chromatic aberration. The IR infrared corresponding technology is also generated accordingly, and there is no need to adjust it again for 24 hours a day. Coke. Therefore, the monitoring system can obtain clear imaging with the assistance of infrared light source.
