Broadband dielectric coating mirror and Laser Mirrors

A broadband 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 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. 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, high damage threshold mirrors, and the coatings on modern mirrorshades.

Our laser dielectric coating mirrors can be flat, concave, convex. The base material of the mirror can be K9, quartz and aluminum.

Product application introduction:
◇Laser module include Line Laser Module, Cross Line Laser Module, Dot Laser Module... Can be used in Industrial marking devices, laser medical equipment, stage lighting and laser targeting devices, Machine vision, Laser Positioning Surveying Instrument, Laser Sight and so on.
◇Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image.
◇Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system.
◇High-quality optical mirrors are available for use with light throughout the UV, VIS, and IR spectral regions. Including Protected Aluminum Mirror, Enhanced Aluminum Mirror, Protected Silver Mirror, Protected Gold Mirror and Dielectric Mirror.
