polygon customized shape 200um thickness Sapphire Optical Window wafer
sapphire advantagement
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.
