Description
| 1. Synthetic Sapphire, the single crystal form of Al2O3, is one of the hardest materials ( 9 Mohs hardness). Because of its structural strength, the sapphire window can be made much thinner than other common optical windows, with better transmittance performance. |
| 2. High thermal stability and excellent thermal conductivity make the sapphire window suitable for the applications in high power. The loss in a sapphire window is less than in another common optical window. |
| 3. Sapphire windows can withstand considerably higher temperatures than most optical windows with zero degradation. |
| 4. Sapphire Windows will not get dark and lose their brilliancy when exposed to UV light. |
| 5. Sapphire windows are extremely stable and resistant to attack by strong acid due to sapphire’s high dielectric constant. |
| 6. Sapphire windows offer wideband transmission from UV to Mid-IR (0.15-5.5µm). |
| All these unique properties make sapphire windows the ideal material for extreme mechanical, chemical & optical applications. |
