Frequently Asked Questions
1. What are the key advantages of using Sapphire Glass over regular glass? Sapphire glass offers extreme hardness (Mohs 9), excellent thermal conductivity (30x higher than ordinary glass), and a wide transmission range from UV to Mid-IR (0.15 - 5.5 μm). It is also highly resistant to chemical corrosion and high temperatures.
2. Can the sapphire windows be customized in shape and size? Yes, we provide customization for various forms including flat, spherical, and aspheric lenses. Sizes range from 1mm up to 1000mm depending on specific requirements.
3. What kind of coatings can be applied to sapphire lenses? Available coating options include Anti-Reflection (AR) to increase transmission, High Reflection (HR) for laser applications, Oleophobic/Hydrophobic for anti-fingerprint protection, and Conductive coatings (like ITO) for electromagnetic shielding.
4. Is sapphire glass resistant to high pressure and temperature? Absolutely. Sapphire has a compressive strength of >2.0 GPa and can operate in temperatures up to 1900°C in vacuum or inert gas environments, making it ideal for high-pressure underwater housing and industrial viewports.
5. What is the standard surface quality for these optical windows? The standard surface finish is 10-5 Scratch-Dig according to MIL-PRF-13830B, with flatness up to λ/10 @ 632.8nm for high-precision optical requirements.
6. What industries typically use sapphire glass components? It is widely used in aerospace, defense, medical endoscopes, high-end consumer electronics (smartwatches/phones), and semiconductor manufacturing equipment.
