Product Description

Sapphire Glass is slightly birefringent in different crystal orientations—meaning it has two refractive indices when light enters the optic. To remove the birefringence sapphire needs to be cut so that the c-axis is parallel to the optical axis. There are different methods of growing sapphire for optics. Standard grade sapphire can be grown via Verneuil and Czochralski methods, whilst for High hardness Sapphire, the Kyropulos method is used. If there are impurities within the lattice, such as iron (Fe) or chromium (Cr) then sapphire can fluoresce when illuminated by UV light. Fluorescence free substrate can be grown from pure seed samples.


Zoolied offers in a variety of Sapphire Optics , such as Optical sapphire rings, Step Glass, Sapphire Rod lens and sapphire tubes. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR). Looking for ideal optical sapphire Manufacturer & supplier? We have a wide selection at great prices to help you get creative. All the Sapphire Glass are quality guaranteed. Zoolied China Origin Factory of Sapphire Optics.
