Corning 0211 Glass Coverslips Technical data

Description

Corning 0211 is a potash, soda, zinc borosilicate glass. Strong chemical durability, uniformity, and thinness are attributes. A thin glass with a firepolished surface, making it suitable for applications without requiring the polishing and grinding process. Color is water white clear, which boasts excellent transmittance.

Excellent flatness
Easy to cut
High light transmission

Applications

The characteristics of this special composition substrate glass makes it suitable for a variety of applications, including:

Microscope cover glass
Thin film substrate
Touch control panels
Protective covers
Flat panel display substrates
