The identification method of sapphire is as follow: Check the logo and glass hardness. Generally speaking, Sapphire Windows is used as the mirror material of high-end watches. Generally, the relevant logo of sapphire glass will be printed on the back cover of the watch, which is expressed as: SAPPHIRE or Sapphire Crystal; in addition, a sharp metal pinpoint can also be used to go. Scratch the edge of the glass. If it feels hard and metallic, and there are no scratches, it should be sapphire glass.


We offer 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).

Synthetic sapphire—sometimes referred to as sapphire glass—is commonly used as a window material, because it is both highly transparent to wavelengths of light between 150 nm (UV) and 5500 nm (IR) (the visible spectrum extends about 380 nm to 750 nm, and extraordinarily scratch-resistant.

The key benefits of sapphire windows are:

Very wide optical transmission band from UV to near-infrared, (0.15–5.5 µm)
Significantly stronger than other optical materials or standard glass windows
Highly resistant to scratching and abrasion
Extremely high melting temperature (2030 °C)


We can supply professional customized service in time and provide cooperation and support of new product development and technology appliance.
