Al2O3 Sapphire Dome K9 Glass Hardness Mohs9 High Pressure Resistivity Optical Windows
Description of Sapphire Dome:
- Sapphire dome refers to the hollow spherical or hemispherical convex structure formed on the sapphire material.
- It is commonly used in optical or decorative applications to give sapphires an attractive appearance and enhance optical properties.
- The specific shape and size of the sapphire dome can be designed and customized according to the needs of the application.
- It can be used in optical components such as lenses, Windows and filters to improve the focusing and propagation of light.
- In addition, sapphire domes are often used in jewelry and jewelry design to add a unique look and luster to sapphire.
- The advantages of sapphire dome include enhancing the beauty of sapphire, improving the refraction effect of light, and reducing
- during preparation and application to ensure that the desired effect and performance are met.
Features of Sapphire Dome:
Sapphire dome has the following advantages over other materials:
- High hardness: Sapphire is the second hardest mineral in nature after diamond and has a very high hardness.
- Scratch resistance: Sapphire has excellent scratch resistance and is relatively not easy to be scratched or damaged.
- Optical transparency: Sapphire has good transparency in the visible and near infrared spectral range.
- High temperature resistance: Sapphire has excellent high temperature resistance to maintain its physical properties.
- Chemical resistance: Sapphire has good corrosion resistance to most common chemicals.
- High refractive index: Sapphire has a high refractive index to change the direction and speed of light propagation.
