The side with protection film is front coated reflector mirror.
What is a front surface coated reflector mirror?
An optical element that reflects a layer of incident light on a surface of an optical glass substrate by vacuum plating a layer of metallic aluminum film.
The front surface is coated with aluminum film and silica protective layer.
The function of silica protective layer is to protect the aluminum film from oxidation.
Because it is the reflection of the first reflecting surface, the reflected image is not distorted, and there is no ghosting, which is a front coated mirror.
