    Why choose the sapphire?

    Sapphire is a precious gemstone, a variety of the mineral corundum, an aluminium oxide (α-Al2O3).

    The only color which sapphire cannot be is red – as red colored corundum is called ruby,

    Commonly,Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (especially integrated circuits and GaN-based LEDs).

    Sapphire is the second hardest crystal next to diamonds and, because of their structural strength,

    sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a

    transmission range from 0.2 - 5.5µm.

    Sapphire Windows Applications
    Sapphire windows are ideal for applications where high pressure, high temperature, high thermal loads, vacuum, scratch resistance, corrosion resistance, small coefficient of friction as well as optical and insulating properties are a consideration.
    Sapphire windows normally need to work under extreme operating conditions, so hard AR coating is required to withstand harsh environmental conditions and improve resistance to scratching.
    Sapphire substrate has a high refractive index, thus usually requires an antireflection coating on sapphire windows for sufficient transmission in the region of interest.
    In some applications where sapphire windows needs to be soldered or bonded to metal. Synthetic Sapphire is a single crystal and high purity, so bare sapphire will not attach to braze or solder alloys on its own. Through solderable metallization on sapphire windows, hermetically sealed optics can be created for harsh or vacuum applications.Sample pictures
