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.
