    Product Description


    Optical Window

    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.

    Product parameters
    glasssurface technologypolishing ,chamfermiddle height random.contace me if you have other specific needsThese round sapphire
    glass crystals come in a variety of thicknesses and diameters, are nearly unbreakable crystals making them highly prized by
    watchmakers. These watch crystals can be glued into most watch cases or pressure fit into most plastic watch crystal gaskets. Each
    sapphire watch crystal comes with a slightly polished bevel edge to give the watch crystal a nice finished look once it has been
    installed. These generic sapphire glass crystals can be used to replace the watch crystals of almost every name brand watch
    popular today, especially high-end watch crystals like those in Rolex watches, saving you both time and money.

    Except for sapphire glass, if you need another watch part, please contact me.Welcome to long-term cooperation.
