• Schott Borofloat® 33 is a high‑quality borosilicate glass renowned for its exceptional properties across a wide range of applications.
  • Manufactured using an advanced micro‑float process, BF33 is a transparent, colorless glass featuring excellent optical quality, a smooth surface and high flatness.
  • BF33 achieves a transmittance of over 90% and exhibits minimal fluorescence across the entire spectrum. These characteristics make it an ideal material for optics, optoelectronics and photonics. Its low thermal expansion and high thermal shock resistance enable it to withstand temperatures up to 450°C, ensuring stability in temperature‑sensitive applications. The glass is also resistant to water, acids and alkalis, making it well suited for the chemical industry and analytical technologies. Notably, Borofloat 33 is widely used in silicon wafer anodic bonding, offering excellent compatibility with silicon substrates for microelectronics and biotechnology.
  • ACA supplies Schott Borofloat® 33 substrates in sizes ranging from 3 inches to 12 inches to meet diverse industry requirements.
