Information and Notes
1. Borofloat will have a slightly higher penetration rate than normal glass. Because of the low expansion coefficient, it can withstand the high temperature of 450~500 degrees.
2. Special shapes or thicknesses can be cut or machined according to customer requirements.
3. The transmittance curves are measurements at 0°of incidence angle. The part that does not penetrate is absorbed by the material of the glass itself.
4. Need higher transmittance? Please refer to anti-reflection processing.
5. The website specifications are for reference only, and shipments are subjected to the specifications confirmed by both parties.
6. The highest safe temperature refers to the temperature at which the glass substrate itself can withstand without breaking under uneven heating or temperature difference. It can be higher in the case of uniform heating or small (slow) temperature difference change.
7. B270, D263T, BOROFLOAT33 are registered trademarks of SCHOTT AG.
