1. Comparison of Sapphire glass
1. suitable for high power,high-pressure applications and vacuum or corrosive atmospheres.
2. Sapphire is a single crystal form of alumina.The material is extremely hard and resistant to attack by srong acid.
3. It has high compressive strength, a high melting point and excellent thermal conductivity.
4. Transmission range is from 150 nm to 5 µm.
5. low distortion,low scatter and excellent parallelism for laser and non-laser applications.
| Material | Properties | Applications |
| Sapphire | Transmission Range: 180-4500nm Refractive Index: 1.755@1000nm Strong Hardness |
Best choice for scratch resistance applications Thinner optics Wide Transmission Range |
| Fused Silica | Transmission Range: 185-2500nm Refractive Index: 1.4858@308nm Low Thermal Expansion Coefficient: 0.54 x 10-6K |
UV to IR spectrum Best choice for thermal resistance application. |
