The working principle of reflective film

Reflective film is an optical material with high reflection characteristics, which can reflect light to a specified direction, thereby reducing the loss of light energy. At present, there are mainly two types of reflective films on the market, one is a metal reflective film, and the other is a dielectric reflective film. The metal reflective film is made of metal materials, such as silver, aluminum, etc., and is generally used in products such as mirrors and reflectors. The dielectric reflective film is made of a dielectric material, and its optical properties are different from those of the metal reflective film.
