Interestingly, by baking sections of the Ceran glass ceramic for 10 minutes at 961 °C, the CTE can be lowered by another five times, from 0.5 ppm / °C to a mere 0.1 ppm / °C.

SPIE Catalyst Award recognizes significant advancements in environmental sustainability SCHOTT pioneered industrial-scale use of 100% hydrogen to produce optical glass without compromising quality.

A hybrid organic-inorganic polymer resin enables the three-dimensional (3D) printing of nanoscale optical-grade glass at temperatures roughly half of what other approaches require, researchers report.

The optical systems company Zeiss has supplied NASA and the ESA with high-grade glass components for years, including lenses for the James Webb Space Telescope and lunar cameras for the Apollo ...
