Pingzhi Optics Camera Window Glass, ar Anti-reflective and Anti-transmission Step Glass, Sapphire Lens
Model: AR
Specification: Customized
Material: Optical glass
Product features:
When light travels from a rarer medium to a denser medium, the reflected light will have a half - wave loss. After coating an AR film on the glass, the optical path difference between the reflected light on the back surface of the film and the reflected light on the front surface of the film is exactly half a wavelength. The reflected light from the front and back surfaces of the thin film cancels out, which is equivalent to increasing the energy of the transmitted light. Moreover, by coating the film on both sides of the glass simultaneously, the reflection effect on both sides of the glass can be reduced at the same time. Since AR glass uses magnetron sputtering coating technology, the sputtered substances form a transparent optical film system through the movement of nanoscale atoms. For example, in the actual - shot pictures above, it can be clearly seen that the glass coated with an anti - reflection film is more transparent, while ordinary glass has a very obvious reflection effect.
The AR film has no impact on the physical properties of the glass itself. Moreover, it has a hardening effect, which is a protection for the glass and has extremely strong adhesion. It can be regarded as having formed an integral whole with the glass. The AR film is sometimes used together with a waterproof and dust - proof film on optical glass and is an ideal choice as a window glass.
