  1. A sapphire optical window is the ideal window material for many UV and IR applications because it can transmit so far into the UV and IR bands. With its thermal and chemical robustness, a sapphire window can be exposed to extreme plasmas and temperatures, far greater than any other material, and continue to transmit high powered UV, visible and IR for years with no degradation. These properties make it an ideal material for UV/VIS/IR sensors, IR surveillance and recon and broad band inspection equipment (especially when abradants are involved).
  2. Sapphire windows are the ideal material for pyrometry. They transmit a wide range of wavelengths while safely isolating hot zones up to 2000C from external room temperature observation; making sapphire windows the ideal sight window for furnaces and high temperature processing equipment.
  3. Medical and dental tools that require UV sterilization and curing and IR thermal processing are typical applications where sapphire windows and transparent tools excel.


    • A supported sapphire window can be taken to 1950C with no change to its shape and minimal reduction to mechanical performance. Sapphire windows are the perfect material for high temperature combustion chambers, gas processing and lamp shields.
    • Sapphire flats are ideal for furniture, boats and standoffs in high temperature furnace systems. Sapphire flats remain flat and dimensionally "perfect" up to 1700C. Because of sapphire's extreme chemical resistance many materials will not stick to sapphire in spite of high temperatures.
    • Sapphire windows and flats maintain the highest temperature rating of all optical materials in both oxidizing and inert atmospheres.
    • Sapphire windows can withstand considerably higher temperatures than the closest runner up material, fused silica, with zero degradation. Fused silica will degrade and devitrify over time at temperatures almost half the maximum operating temperature of sapphire.

About Our Company & Factory 


    ZMKJ has been fabricating micro to large sapphire windows, sight glasses and flats for over 10 years. Although sapphire is often more costly than glass and other transparent materials, its exceptional properties can ultimately save money and reduce critical down time, often eliminating the need for PM periodic replacements.

    We are also specialize in providing a varity of materials wafers, substrates, components, products are widely used in electronics, optics, optoelectronics and many other fields. We've been working closely with many domestic and oversea universities, research institutions and companies, provide customized products and services for their R&D projects.

It's our vision to explore and develope cutting edge application of new materials with customers together.
