Frequently Asked Questions

What is the primary material used in these lenses?

The lenses are made from high-purity Synthetic Sapphire Glass (Single Crystal α-Aluminium Oxide), known for its extreme hardness and excellent optical clarity.

How scratch-resistant is sapphire glass?

Sapphire glass has a Mohs hardness of 9, making it the second hardest natural material after diamond. It is highly resistant to scratches and impact, ideal for harsh industrial environments.

What is the light transmission range of your sapphire windows?

Our sapphire optical windows support a wide transmission range from 0.15 μm (Deep UV) to 5.5 μm (Mid-Infrared), with internal transmittance typically exceeding 85%.

Can the lenses be customized with specific coatings?

Yes, we offer various coating options including Anti-Reflection (AR), High Reflection (HR), Oleophobic/Hydrophobic (anti-fingerprint), and conductive ITO coatings to meet specific application needs.

What industries typically use high-precision sapphire lenses?

These lenses are widely used in high-end consumer electronics (smartwatches, camera covers), aerospace & defense (missile domes, pod windows), medical devices (endoscopes), and the semiconductor industry.

What temperature range can these sapphire windows withstand?

Sapphire glass remains stable at very high temperatures, with a melting point of 2040 °C. It can operate at up to 1900 °C in vacuum or inert gas environments, and approximately 1000 °C in air.
