polygon customized shape 200um thickness Sapphire Optical Window wafer
Chemical resistance – sapphire is highly inert and resistant to attack in most process environments.Mechanical properties – High Strength – with strength and stiffness 6 times higher than quartz, combined with excellent wear and scratch resistance – sapphire becomes the high performance choice.
Optical properties – with transmission from 200 to over 3500 nm, sapphire is used in applications spanning from UV to visible to short wave infra red (SWIR).
Thermal properties – usable to temperatures near 2000 C.
Electrical properties – Sapphire provide a high, stable dielectric constant with the electrical insulation required for electronic substrates, RF and microwave transmitting windows and tubes.
Surface properties – with high hardness and uniformity sapphire can be polished to very tight flatness levels 1/10th and eve 1/20th wave flatness and Angstrom level surface finishes.
Wear properties – high strength and chemical durability combine to enable the production of dimensionally and optically stable components for long life use.

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.
