Frequently Asked Questions

Q1: What are the main benefits of using sapphire glass over standard glass?

Sapphire glass offers extreme hardness (Mohs 9), excellent thermal conductivity, and a wide transmission range from UV to mid-infrared. It is highly resistant to scratching and chemical corrosion.

Q2: Can the size and shape of the optical lenses be customized?

Yes, we provide customization for sizes ranging from 1mm to 1000mm. Shapes include flat, spherical, and aspheric geometries tailored to your specific requirements.

Q3: What types of optical coatings do you offer?

We offer Anti-Reflection (AR), High Reflection (HR), Oleophobic/Hydrophobic, and Conductive (ITO) coatings to enhance performance and durability.

Q4: What is the maximum operating temperature for sapphire windows?

Sapphire can withstand up to 1900°C in vacuum or inert gas environments and approximately 1000°C in standard air before surface devitrification concerns.

Q5: Is sapphire glass resistant to chemicals?

Yes, it is insoluble in water and highly resistant to most strong acids and bases. However, it is not resistant to Hydrofluoric Acid (HF) or hot Phosphoric Acid.

Q6: What precision levels can you achieve for surface finish?

We can achieve high-grade surface finishes up to 10-5 Scratch-Dig and flatness of λ/10 @ 632.8nm for high-precision optical applications.
