About Infrared Lens
The infrared lens uses a special optical glass material, and uses the latest optical design method to eliminate the focal plane shift of visible light and infrared light, so the light from visible light to infrared light can be imaged on the same focal plane, so that the images are all Can be clear.
In addition, the IR infrared lens also uses a special multi-layer coating technology to increase the transmittance of infrared light, so the camera with the IR lens can monitor at a farther distance than the camera with the ordinary lens at night, and the effect is better.
The range of application of IR lens is very wide, it can be used not only for special purpose of infrared correspondence, but also as general lens. In other words, according to different usage occasions, the infrared corresponding lens can be used flexibly with conventional color cameras, black and white cameras, and day and night conversion cameras.
Black-and-white cameras do not have infrared cut filters, but the spectrum of sunlight also contains infrared light, so even under daylight conditions, the imaging of black-and-white cameras will be interfered by infrared rays. Therefore, matching with an infrared corresponding lens can effectively improve the imaging quality.
Where it comes from:
In order to meet the needs of 24-hour monitoring, many places not only require cameras to be able to complete monitoring tasks during the day, but also to be able to present clear images at night. Moreover, in recent years, infrared cameras and infrared lights have become popular, and the prices of day and night cameras and high-definition color cameras have dropped to a certain extent, providing lens manufacturers with a large number of market opportunities. In this way, the IR surveillance camera lens was born.
Infrared Lens Features:
1. The focus infrared light of the IR surveillance camera lens 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, which eliminates the focal plane shift of visible light and near-infrared light.
3. The IR lens uses a special ED lens to solve the problem of "running out of focus" of ordinary electric zoom lenses under infrared light conditions.
4. The IR lens uses a special coating design and the use of special optical materials so that the light in the 350-950nm range can be well corrected for chromatic aberration. The IR infrared corresponding technology is also produced accordingly, and it does not need to be adjusted again for 24 hours a day. coke. Therefore, the monitoring system can obtain clear imaging with the assistance of the infrared light source.
