Cut Off Filter
Infrared cut filter 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 filter, mainly used in mobile 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 cutoff filter, 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 cut filter 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 filter glass, mainly used in mobile 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 end filter, 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.
