Frequently Asked Questions

What makes Sapphire Glass superior to ordinary optical glass?

Sapphire glass features a Mohs hardness of 9, making it nearly scratch-proof (second only to diamond). It also offers a much wider transmission range (0.15–5.5 μm) and significantly higher thermal conductivity.

What is the maximum operating temperature for sapphire windows?

Sapphire windows can withstand up to 1000°C in air and up to 1900°C in vacuum or inert gas environments, making them ideal for high-temperature industrial viewports.

Can I customize the dimensions and shape of the lens?

Yes, we offer customization for sizes ranging from 1mm to 1000mm. Shapes can be flat, spherical, or aspheric depending on your specific requirements.

What types of coatings are available?

We provide several coating options including Anti-Reflection (AR) to increase transmittance, High Reflection (HR) for lasers, and Oleophobic/Hydrophobic coatings for anti-fingerprint properties.

Is sapphire glass resistant to chemical corrosion?

Yes, sapphire is highly stable and insoluble in water, resistant to most strong acids and bases. However, it is not resistant to hydrofluoric acid (HF) or hot phosphoric acid.

What industries typically use sapphire optical windows?

Major industries include medical (endoscopes), aerospace (missile domes), electronics (smartphone sensors), and high-power laser research.
