Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as crystal materials in specific field such as space technology where scratch or high temperature resistance is required
Properties of Sapphire Glass
Optical crystals are used as viewports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical crystals are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire crystal has several unique properties that make it the ideal material for these applications.
| 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 crystal can be made much thinner than other common optical crystals, with better transmittance performance. |
| 2. High thermal stability and excellent thermal conductivity make the sapphire crystal suitable for the applications in high power. The loss in a sapphire crystal is less than in another common optical crystal. |
| 3. sapphire crystals can withstand considerably higher temperatures than most optical crystals with zero degradation. |
| 4. sapphire crystals will not get dark and lose their brilliancy when exposed to UV light. |
| 5. sapphire crystals are extremely stable and resistant to attack by strong acid due to sapphire's high dielectric constant. |
| 6. sapphire crystals offer wideband transmission from UV to Mid-IR (0.15-5.5µm). |
| All these unique properties make sapphire crystals the ideal material for extreme mechanical, chemical & optical applications. |

Why Choose our sapphire crystal
sapphire crystal are ideal for applications where high pressure, high temperature, high thermal loads, vacuum, scratch resistance, corrosion resistance, small coefficient of friction as well as optical and insulating properties are a consideration.
sapphire crystal normally need to work under extreme operating conditions, so hard AR coating is required to withstand harsh environmental conditions and improve resistance to scratching.
Sapphire substrate has a high refractive index, thus usually requires an antireflection coating on sapphire crystal for sufficient transmission in the region of interest.
In some applications where sapphire crystal needs to be soldered or bonded to metal. Synthetic Sapphire is a single crystal and high purity, so bare sapphire will not attach to braze or solder alloys on its own. Through solderable metallization on sapphire crystal, hermetically sealed optics can be created for harsh or vacuum applications.
