High Transmittance Digital Cameras Video Handsets Visible Light Transmission Infrared Cut-Off Filter
Infrared cutoff filter is an optical film with high and low refractive index that is altemately plated on the optical substrate using precision optical coating technology to achieve high permeablity in visible region of 400 to 630 nanometers and near infrared cutoff of 700 to 1100 nanometers. It is mainly used in the digital imaging fields such as camera of mobile phone, built-in camera of computer and car camera. Used to eliminate the effect of infrared light on CCD or CMOS imaging
