Sapphire is one of the hardest materials, and possesses very good transmission during the range of visible and near IR spectrum.It is widely used as optical window in infrared and far infrared military equipments, apparatus and instruments of satellite and space technology, and navigation and spaceflight, such as night infrared scope/sight and night vision camera, etc.The sapphire crystal window is intensively applied in high-tech fields.
Sapphire optical windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. Sapphire, a single crystal form of Al2O3, is resistant to attack by strong acids due to its high dielectric constant. It has high compressive strength and a high melting point. It is also resistant to UV radiation darkening.
Comparison of optical window materials
| Material | Properties | Applications |
| BK7 | Transmission Range: 330-2100nm Refractive Index: 1.5164@588nm | Most popular and low cost Visible and near IR spectrum applications |
| 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. |
| Sapphire | Transmission Range: 180-4500nm Refractive Index: 1.755@1000nm Strong Hardness | Best choice for scratch resistance applications Thinner optics Wide Transmission Range |
| Calcium Fluoride | Transmission Range: 170-7800nm Refractive Index: 1.399@5000nm Little Hygroscopic Susceptibility High Thermal Expansion Coefficient: 18.85 x 10-6K | IR laser applications |
| MgF2 | Transmission Range: 120-7000nm Refractive Index: 1.376@700nm | UV laser applications |
