What is a front surface coated reflector? An optical element that reflects a layer of incident light on the surface of an optical glass substrate by vacuum coating a layer of metal aluminum film. Because it is the reflection of the first reflection surface, the reflected image has no distortion or ghosting, which is the pre coated reflector. The front surface is coated with an aluminum film and a silicon dioxide protective layer. The function of the silica protective layer is to protect the aluminum film from oxidation.
