Nerasil® is a non-transparent fused quartz. It is designed as an absorber. The doping level is low enough that the mechanical properties are comparable to transparent fused quartz - a valuable member of the Vitreosil® family.
The benefits of Nerasil® include:
- Low transmission at even low material thickness
- Machinable as transparent fused silica
- Comparable thermal properties allowing joining with transparent fused quartz
