1. Thinner and Stronger than Standard Glass Windows
2. Transmits Wavelengths Ranging From UV to Mid-Infrared
3. Features Extreme Surface Hardness and Chemical Resistance
Sapphire crystals are the most beautiful of crystals — highly scratch-proof, easy on the eyes, and not expensive. They are more commonly seen on high-end watches and most limited-edition watches.
Sapphire crystals are extremely scratch-resistant and are considered a gem in the world of horology. Watch modders and collectors alike love a timepiece with a sapphire crystal, as it makes for a clean and beautiful look. The crystals not only protects your watch’s dial and face but also enhances the overall aesthetic.
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm
