Brand Overview
Nerasil® is a black fused silica that can be machined just like transparent fused silica. Its special optical properties make it an excellent choice for all applications where a high degree of absorption is required.
Benefits of Nerasil®
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 even at low material thickness
- Machinable as transparent fused silica
- Comparable thermal properties with transparent fused silica also allow bonding between these two types
Fields of Applications
Nerasil® is suitable for all optical applications where a high degree of absorption is required.
Some examples are:
- Mirror substrates (as Nerasil® suppresses unwanted transmissionen)
- Ferrules for optical elements to suppress stray light
- Back sides of cuvettes to eliminate signals from backwall reflection
