Sapphire Optical Properties and Sapphire Optical Transmission
Sapphire is a highly durable material with exceptional optical properties, including a broad transparency range from ultraviolet to infrared, a high refractive index, and strong resistance to damage. These qualities make it suitable for diverse applications such as high-power lasers, missile guidance, optical windows, smartphone screens, underwater uses, and watch crystals, while also offering notable mechanical, thermal, and electrical characteristics.
Sapphire’s valuable optical properties include a high refractive index, strong resistance to damage, and broad transparency. It is suitable for many optical applications because it can transmit light across the entire ultraviolet (UV) to infrared (IR) spectrum. It is extremely hard, making it resistant to scratches and abrasion. Additionally, sapphire’s high resistance to chemical corrosion, abrasion, and radiation makes it ideal for use in harsh environments.
Typical applications for sapphire include:
- High-power laser applications
- Missile guidance systems
- Optical windows
- Smartphone screens
- Underwater applications
- Watch crystals
