Knowledge & Service >> Sapphire Windows Properties |
| |
| Sapphire Window made of Synthetic sapphire features exceptional performance of high hardness, high strength, scratch resistance, high temperature resistance, chemical durability and excellent transmission bandwidths. |
| Sapphire Windows Properties |
| Optical Windows
are used as viewports to protect other components within an optical assembly, instrument or laser. In certain applications, optical windows are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire window has several unique properties that make it ideal material for these applications. |
| Synthetic Sapphire, the single crystal form of Al2O3, is one of the hardest materials ( 9 Mohs hardness). Because of its structural strength, sapphire optical windows can be made much thinner than other common optical windows, with better transmittance performance. |
| High thermal stability and excellent thermal conductivity make sapphire window suitable for the applications in high power. The loss in a sapphire window is less than in other common optical window. |
| Sapphire windows can withstand considerably higher temperatures than most optical windows with zero degradation. |
| Sapphire Windows will not get dark and lose their brilliancy, when exposure to UV light. |
| Sapphire windows are extremely stable and resistant to attack by strong acid due to sapphire’s high dielectric constant. |
| Sapphire windows offer wide band transmission from UV to Mid-IR (0.15-5.5µm). |
 |
| Benifits of Sapphire Windows |
| Wide band transmission from UV to Mid-IR (0.15-5.5µm) |
| Stronger than other optical materials windows |
| Highly resistant to scratching and abrasion (9 Mohs scale) |
| Extremely high melt temperature (2030°C) |
| Resistant to attack by strong acid |
| High thermal stability and excellent thermal conductivity |
|
| Application of Sapphire Windows |
| All these unique properties makes sapphire windows the ideal material for extreme mechanical, chemical & optical applications. |
| Sapphire windows can be metalized to create hermetically sealed optics which are ideal for harsh or vacuum applications. |
