Corning Incorporated

Whether for lithography, vision correction, or industrial applications, excimer laser performance is dependent on fluoride crystal quality and durability.

Corning uses specialized fluoride crystal growth processes developed over more than 50 years to maximize radiation durability of fluoride crystal materials. For harsh laser exposure levels, or where maximizing optic lifetime and equipment uptime are critical, Corning® Laser Durable Grade Calcium Fluoride is the material of choice.

We have also expanded our optical material portfolio, Corning® Optical Grade Calcium Fluoride, an addition to the fluoride crystal product family for Corning, is an ultra-clear, durable crystalline material engineered to withstand and direct the short-wavelength laser light in photolithography. Corning processes the product into pre-finished blanks for lenses to enable this precise imaging.

Corning’s proprietary fusion draw process creates ultra-flat substrates with precise thickness control. This manufacturing platform produces large-sized glass substrates up to Gen 10.5, enabling customized substrate offerings that maximize glass utilization and minimize glass handling.

Available in panel or wafer format, our flexible design solutions and manufacturing processes help lower customers’ costs, giving them more glass and reducing waste. From industry leading materials like Corning® Eagle XG® Glass and Corning Lotus™ NXT Glass, our high-quality array of glasses feature superior surface quality and tightly-controlled total thickness variation (TTV). We offer custom quantities of cost-effective form factors or full sheets of Gen 5 (1300mm x 1100mm) and above.
