IR lens is infrared lens,It uses a special optical glass material and the latest optical design method to eliminate the visible light and infrared light focal plane deviation.Therefore, from the visible to the infrared region of the light can be focus on the same plane imaging at the same time the image can be clearer.In addition, infrared lens also uses a special multilayer coating technology In order to increase the transmission rate of infrared ray, so the camera with infrared lens
Can monitor longer diatance than camera with normal cctv lens,at the same time,it has better effect.
Advantage of the infrared lens
- infrared camera lens focus the infrared light and visible light on the same point.And has clearer image.
- IR lens uses the latest optical design and special optical glass material (LD optical glass) technology, eliminating the visible light and infrared focal plane deviation
- IR lens using special ED lens, to solve problem that the ordinary electric zoom lens "running focus" in the infrared light.
- Infrared lens makes the wavelength range of 350-950nm light can be very good to correct aberrations by use the special coating design and special optical material.so the camera can work 24 hours without focusing again.Therefore, the monitoring system can obtain the clear image under the assistance of the infrared light source.
Application of infrared lens
Infrared lens has a very wide range of applications, which can be used as a special purpose, and also can be used as a common cctv lens.In other words, in accordance with the use of different occasions, the infrared lens can be used with the conventional color camera, black and white cameras, as well as day and night camera flexibly.
Black and white camera has no ir cut filter,but the sun light contains infrared light. so even in day light conditions, black and white camera image will be affected by infrared light interference.
Therefore, equipped with infrared lens can improve the image quality.
Future development of infrared lens
infrared lens technology is not a problem, the impact of its development may still be in the price.To be sure, the infrared surveillance camera lens is still a large demand for products in the next few years, once the yield up, the cost will be low. IR lens will be the mainstream of the future.
