Frequently Asked Questions

Is sapphire glass made from real gemstone sapphires?

Sapphire glass is a synthetic sapphire crystal created by crystallizing aluminum oxide at high temperatures. It has identical physical properties to natural sapphire but is man-made for industrial and optical applications.

What is the primary advantage of using sapphire glass?

Its core advantage is an exceptional Mohs hardness rating of 9, making it highly resistant to scratches from everyday materials. It also offers excellent optical transmittance from UV to Mid-IR.

Is sapphire glass shatterproof?

While extremely hard and scratch-resistant, sapphire glass can be brittle. It is specialized for scratch prevention rather than high-impact drop protection. Structural designs like domed shapes are often used to improve resistance.

What is the light transmission range of this material?

Sapphire glass has a very broad transmission range, typically from 0.15 μm to 5.5 μm, covering Deep UV, Visible, and Mid-Infrared spectrums.

Can sapphire glass withstand high temperatures?

Yes, it has a very high melting point of 2040°C. It can operate at temperatures up to 1900°C in vacuum or inert environments and approximately 1000°C in air.

What coating options are available?

We offer various coatings including Anti-Reflection (AR) to increase transmission, High Reflection (HR) for lasers, and Oleophobic coatings for anti-fingerprint properties.
