Optical Materials | Superior Optical Glass | Corning

Corning is a leading supplier of fused silica and ultra-low expansion glass and fluoride crystals in bulk and part form for applications in semiconductor component optics, industrial, and imaging applications.

Superior Size and Homogeneity

Test

Corning Advanced Optics leverages a long legacy in glass materials science understanding through vapor deposition to produce high-quality glasses for use in semiconductor component optics. We offer more than five types of glass materials that offer remarkable, and oftentimes superior characteristics for applications from high power lasers, laser debris shields, small parts, and bulk parts to lithography materials. Our products offer considerable application flexibility and can often be customized across glass grades, dimensions, and cost.

Corning also specializes in shaping fluoride crystals and fused silica into laser optic components, including flats, prisms, lenses, mirrors, and optics with specialized surface figures. Cutting-edge technology for finishing and coating is available for maximizing optic lifetime for highly transmissive, highly reflective, or partially reflective optics.

Key Benefits of Corning's Boule-Based Manufacturing Process

Whether for lithography, vision correction, or industrial applications, excimer laser performance and up time are dependent on fluoride crystal quality. Corning uses specialized fluoride crystal growth processes developed over more than 50 years to maximize radiation durability of fluoride crystal materials. For the harshest laser exposure levels, or where maximizing optic lifetime and equipment uptime are critical, Corning Calcium Fluoride (CaF2) is the material of choice. Corning also offers design engineering, fabricating, polishing and coating capabilities.
