    标准平面反射镜

    Optical Surfaces regularly supplies reference flats and mirrors world-wide. Flats are often used as a reference or, to fold a system in order to make it more compact, or to re-direct light at a desired direction.
    The tables below can be used as a guide to our standard specifications for parameters such as size, material, surface accuracy and quality, microroughness, dimensional tolerances etc.

    Special options include:
    • Non circular shapes
    • Surface accuracy of lambda/20 P-V at 633nm.
    • Surface Quality: 10/5
    • Microroughness <1nm RMS
    • An extensive range of special coatings available including high power and femtosecond laser for various applications and to MIL-C-13508
    • Light-weighting options
    • Engineering and mounting service

    Interferograms and analysis are typically supplied for flats with surface accuracy of lambda/4 P-V at 633nm or better. Slope errors are such to be insignificant in Schlieren and Reference applications.
