In the manufacture of our optical filters we employ both conventional Physical Vapor Deposition (PVD) multi-layer coatings combined with a high quality encasing technique to ensure environmental stability, Plasma-assisted Deposition techniques to produce “hard” coatings that exhibit unrivaled durability in harsh environments and Sputter Coatings to produce state of the art filter solutions.
We also offer e-beam evaporation of various materials for the manufacture of special thin-film coatings.
