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.
