For over 100 Years, Heraeus has been providing breakthrough solutions for the world’s most challenging optical and optical fiber applications – where highly pure fused silica is an absolute necessity.
Our quality, reliability, repeatibility and scalability also provide the clear performance leadership across the different product areas:
Our products include:
- Prism, Beam Splitter, Beam Combiner and 3D Optics
- Highest Power NIR Laser Optics
- High Power Laser Transmission
- Multi kW Laser Fibers

Heraeus Covantics NIR grades support kw-MW Laser Systems with:
→ Ultra-pure, extremely low OH material for highest transmission, lowest absorption in NIR (>800nm)
→ Best homogeneity and minimized thermal lensing achieve best beam quality
→ Bubble free material produced in a repeatable & tracible process insures a very high Laser Damage Threshold
