In the manufacture of our optical filters we employ both conventional Physical Vapour Deposition (PVD) multi-layer coatings combined with a high quality encasing technique to ensure environmental stability and plasma-assisted deposition techniques to produce “hard” coatings that exhibit unrivaled durability in harsh environments.
We also offer e-beam evaporation of various materials for the manufacture of special thin-film coatings.
- Physical Vapour Deposition (PVD)
- Plasma-assisted deposotion techniques
- e-beam evaporation (for special thin film coatings such as Au, Al and various compounds)
