Optical Mirror PARAMETER:
A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coatingwith 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. Mirrors of this type are very common in optics experiments, due to improved 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.
Dielectric mirror is an optical mirror made of thin layers of dielectric coating deposited on an optical substrate. We offer dielectric laser mirrors for fixed, narrowband or broadband wavelength applications covering wavelength ranges from UV to IR. Wide selection of round, elliptical or custom shapes as well as flat, spherical, cylindrical surface mirror.
