Schott to Offer Large Format Sapphire Glass for Security Applications

SCHOTT will be presenting new forms of delivery for sapphire material at LASER 2011. Customers qualified large format polished and coated panes of up to 300 mm in diameter only recently. In the future, these products will also be put to use in security applications under extreme environmental conditions.

Sapphire glass is the second hardest transparent material next to diamonds. It is made of high purity aluminum oxide that is produced synthetically. This extremely scratch-proof and heat-resistant material offers high transmission in the wavelength range of 0.5 up to approx. 6.25 ìm.

By introducing new forms of delivery, SCHOTT is now also expanding the range of applications. The company manufactures sapphire glass panes that are up to 300 mm in diameter. These are then individually polished and coated to meet specific customer requirements.

The formats can be designed rather freely, from round to square, and feature either a curved or a flat surface. The processing quality ranges from standard to optical quality. Sapphire glass is used in high-quality watches, but also in optical, chemical, analytical, medical and security technologies.
