Polished Glass Substrates

BEN_2332

Bullen single and double-sided polished glass wafers set the standard for quality for your MEMS and optoelectronic applications.
Bullen glass wafers exhibit:
  • Surface finish Ra< 15A and TTV < 9 microns

  • Minimal to no sub-surface damage means premium performance for anodic bonding applications and post-polish etching processes

  • Superior flatness and parallelism
