Corning Gorilla Glass features scratch resistant surface, superior durability

Gorilla Glass is now available from Valley Design. Wafers and substrates are readily available in standard or custom sizes in the following thicknesses: .55mm, .7mm, 1.1mm, 1.3mm, 2.0mm. Standard wafer diameters are 2”, 3”, 100mm, 125mm, 150mm, 200mm, 300mm. Sheet stock is available as large as 423mm x 460mm and is transparent to approximately 60/40 scratch/dig. For custom sizes, Valley can fabricate parts from as small as 0.127mm square up to 400mm diameter and anything in between. If your application requires, Valley can custom thin these thicknesses to your specification to as thin as < 25um. Improved optical surface finishes and flatness are also available. Valley can also supply Dragontrail™ glass which is manufactured by Asahi Glass Corporation, and is similar in properties and performance to Gorilla glass.
