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
