Frequently Asked Questions

What are the main advantages of using sapphire glass over standard glass?

Sapphire glass offers extreme surface hardness (Mohs 9), high thermal conductivity, and a broad transmission range from UV to mid-infrared, making it ideal for harsh environments and high-precision optics.

Can the sapphire windows be customized in terms of shape and size?

Yes, we provide full customization for dimensions ranging from 1mm to 1000mm, including flat, spherical, and aspheric forms to meet specific instrument requirements.

What types of coatings can be applied to these sapphire components?

We offer various coating options including Anti-Reflection (AR), High Reflection (HR), Oleophobic/Hydrophobic, and Conductive (ITO) coatings.

Is sapphire glass resistant to chemical exposure?

Sapphire is highly chemically inert and insoluble in water. It is resistant to most strong acids and bases, except for Hydrofluoric acid (HF) and hot Phosphoric Acid.

What is the typical surface quality provided?

Our standard surface finish is 10-5 Scratch-Dig according to MIL-PRF-13830B, with high-grade options available up to 20-10 for demanding applications.
