PURPOSE:To give an arbitrary color tone to a reflection mirror and to protect a driver from fatigue due to dazzle by providing a three-layered structure consisting of substrate glass, a metallic film and a transparent dielectric to the mirror. CONSTITUTION:A metallic film 2 of an Ni-Cr alloy forming a light reflecting surface is vapor-deposited on a substrate 1, and a transparent dielectric film 3 of TiO2 is vapor-deposited on the film 2. When light enters the film 3 from the direction of an arrow L, light reflected from the surface of the film 2 and light reflected from the surface of the film 3 interfere with each other, producing coloring and antidazzling effects. The color and the reflectance depend on the optical thickness of the film 3, and the depth of the color depends on the refractive index. |
