A dielectric mirror is a type of a mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of optical material (e.g. glass). By careful choice of the type and thickness of the dielectric layers, we can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques.
Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Broadband Dielectric Mirrors of this type are very common in optics experiments, due to improved and advanced techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshades.
