Overview of color mirrors

Jul 14, 2021

A photochromic glass is a glass made of color-changing glass, which changes its color under the irradiation of light of an appropriate wavelength, and restores its original color when the light source is removed. It is also called photochromic glass or photochromic glass. .

Color-changing glass is made by adding light color material to glass raw material. This material has two different molecular or electronic structure states. It has two different absorption coefficients in the visible light region. Under the action of light, it can transform from one structure. To another structure, resulting in a reversible change in color. The characteristic of silver halide color changing glass is that it is not easy to be fatigued. After more than 300,000 times of light and dark changes, it still does not fail. It is a commonly used material for making color changing glasses. Color changing glass can also be used for information storage and display, image conversion, light intensity control and adjustment etc.

Chromochromic mirror is irradiated by ultraviolet rays and short-wave visible light under sunlight, the color becomes darker and the light transmittance decreases. The light transmittance of the lens is improved indoors or in dark places, and the color fades and brightens. The photochromism of the lens is automatic and reversible. The color changer can adjust the transmittance through the color change of the lens, so that the human eye can adapt to the change of ambient light, reduce visual fatigue, and protect the eyes. The color changer is divided into no base color film and light before color change. There are two colors of base color film. The color after discoloration is mainly gray and brown.
