  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 Diameter 300mm Sapphire Optical Windows Clear Color 1mm - 100mm Thickness 0 nd 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.
  4. .high temperature resistant, Sapphire Round / Rectangular Optical Window can work under 1200°C continuously,and in short time can even work under 1450°C,its softening temperature is 1650°C,and the melting temperature is 1750-1800°C.

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.
