    Mirrors are used to fold, bend and focus optical beams.They are usually processed into round, rectangle.Other shapes of mirror are available upon your request.

    Selecting the proper mirror for your application requires making a number of choices. A few of the many considerations include: Reflectivity, Laser Damage Resistance, Coating Durability, Thermal Expansion of the substrate, Wavefront Distortion, Scattered Light, and certainly Cost.

    Featured substrate materials: Pyrex is an excellent mirror substrate due to its low coefficient of thermal expansion and resistance to thermal shock. When high stability is critical, Zerodur is the best choice for its zero thermal expansion. UV Fused Silica has a thermal expansion coefficient lower than Pyrex, yet is more expensive. Because of its excellent transmissive properties, it is often reserved for transmissive mirrors as well as high-energy laser mirrors.

    CZ Silicon is frequently used for laser mirrors because of its high thermal conductivity and low density.
