Conventional car's mirrors are made of a mercury or silver plate. Inasmuch as reflecting the reflection totally, driving at night becomes hard for drivers. In addition, the working environment with erosion and humidity affects the useful life of these mirrors. Meanwhile, the advent of nanotechnology has led to producing mirrors with a metal coating which decreases the reflected light with keeping image resolution. While these mirrors maintain the quality in different weather conditions, ease driving at night via preventing of complete reflection of light. Metal coating mirrors are mirrors (light reflectors) with a thin coating of metal which is produced using the evaporation or sputtering methods. The metal coating is applied on a glass or metal plate. Current production is a car's mirror with nanometric chromium coating which is produced via the PVD method.
