IR coating/IR-CUT FILTER film:Cut-off film is a film with high reflection to the light of specific band by designing and adjusting the structure and thickness of the film layer.
At present, we can often see products coated with cut-off film in our life. For example, the anti-blue light cell phone screen is coated with blue light cut-off film, that is, the film effect presents a high inverse effect to the blue light band, and a high transmission effect to other visible light bands.



By alternately plating titanium oxide and silicon oxide on the glass substrate, we designed and adjusted the number of layers and the thickness of each layer to make the blue light of the wavelength of 400-450nm show a high reflectivity, while the other visible light of the wavelength of 500-700nm show a high transmittance, so as to achieve the anti-blue light effect, as shown in the following figure:
