Concept

IR lens is an infrared lens. It uses special optical glass materials, and uses the latest optical design methods to eliminate the focal plane offset of visible and infrared light. Therefore, light from visible light to infrared light can be imaged in the same focal plane, making images clear. In addition, the IR infrared lens also uses a special multi-layer coating technology to increase the transmittance of infrared light. Therefore, the camera with IR lens can monitor a longer distance at night than the camera with ordinary lens, and the effect is good.

Background  

In order to adapt to the 24-hour monitoring requirements, many places require cameras not only to complete monitoring tasks in the daytime, but also to present clear images at night. In recent years, infrared cameras and infrared lamps have been widely used, and the prices of day and night cameras and high-definition color cameras have declined to a certain extent, providing lens manufacturers with a large number of market opportunities. In this way, the IR surveillance camera lens was born.

Advantage

1. IR monitoring camera lens focus infrared light is consistent with visible light, and 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 offset of visible light and near-infrared light.

3. IR lens adopts special ED lens to solve the problem of "out of focus" of ordinary electric zoom lens under infrared light.

4. The IR lens is designed with special coating and the application of special optical materials, so that the color difference of light in the 350-950nm band can be well corrected. The IR infrared corresponding technology is also generated accordingly, and it does not need to focus again when working 24 hours a day. Therefore, the monitoring system can obtain clear imaging with the aid of infrared light source.

Scope of application

IR lens has a wide range of applications, which can be used for both special infrared applications and ordinary lenses. In other words, depending on the use occasion, the infrared corresponding lens can be flexibly used together with the conventional color camera, black and white camera and day night conversion camera. The black and white camera does not have an infrared cut-off filter, but the spectrum of sunlight also contains infrared light, so even in daylight, the imaging of the black and white camera will be interfered by infrared light. Therefore, the matching of infrared corresponding lens can effectively improve the imaging quality.
