Cut Off Filter

BRD Optical Co. Ltd. has state-of-the-art, modern technology machines for manufacturing and inspecting all kinds of precision optics. Our company occupies an area of 2,000 square meters, supported by 120 workers. BRD Optical as one of the best precision optical components companies was founded in 2004, and is located in the city of Changchun-the optic base of China with a beautiful view and profound optical culture.

Infrared lc filter cutoff is the use of precision optical coating technology on optical substrate plating alternately high and low refractive index of optical film, achieve high visible light area (400-630 nm), near infrared (700-1100 nm) as optical uv cut off filter, mainly used in mobile phone cameras, computer are photographed a built-in camera, car camera digital imaging field, is used to eliminate the influence on CCD/CMOS imaging infrared light.By imaging system with ir cut filter material, block the part of the interference imaging quality of infrared light, can make the image more in line with the human eye made by the best feeling.

Description Of Cut Off Filter
Infrared rc filter cutoff calculator is the use of precision optical coating technology on optical substrate plating alternately high and low refractive index of optical film, achieve high visible light area (400-630 nm), near infrared (700-1100 nm) as high pass filter cutoff glass, mainly used in mobile phone cameras, computer are photographed a built-in camera, car camera digital imaging field, is used to eliminate the influence on CCD/CMOS imaging infrared light.By imaging system with infrared rc filter cutoff, block the part of the interference imaging quality of infrared light, can make the image more in line with the human eye made by the best feeling.
