Audited Supplier Round optical glass windows(K9 CaF2,MgF2,Ge,ZnSe,Mono Si,ZnS,quartz)s
Optical windows refer to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows are applied for protecting fragile optical components inside an equipment, they are adopted to isolate two physical environments while allowing light to pass.
Optical window materials comparison:
| Material | Properties | Applications |
| BK7 | Transmission Range:330-2100 nm Refractive Index:1.564@588nm |
Most Popular and low cost Visible and near IR spectrum applications |
| Fused Silica | Transmission Range:185-2500nm Refractive Index:1.4858@1308nm 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 High Thermal Expansion Coefficient:18.85 x 10-6K |
IR laser applications |
| MgF2 | Transmission Range:120-7000nm Refractive Index:1.376@700nm |
