SwissOptic 3D测量系统

Coatings & Microstructures. Application-Specific Surfaces.

We produce superior coatings for various applications. The spectral range runs from UV (190 nm) into the infrared range (5 µm; up to 12 µm for metal mirrors).

With our modern coating technologies (PVD with and without ion-assistance), we have extensive coating capacity with in-situ monitoring technologies (oscillating quartz and optical broadband monitoring) in order to provide you with specific solutions. The most modern measurement and testing techniques allow us to analyze even very demanding specifications.

Our coating services include

  • Coatings on typical optical glass as well as quartz, sapphire, CaFl2, Si, Ge, ZnS
  • Formats from diameters of 3 mm upwards, planar components up to 400 mm in length
  • Also, glass fibers, cemented substrates, crystals
  • Spectral range of 190 – 5,000 nm, mirrors from 190 nm – 12 µm
  • Conductive coatings (ITO), anti-glare absorption layers (e. g. black chrome, chrome-free as well)
  • High laser damage thresholds (LIDT)
  • Strict coating tolerances
  • ROHS compliant

 

In addition, we design and manufacture micro-structured optical components according to your wishes.

Through the use of various lithographic processes (lift off, etching processes, contact prints, proximity copies, imaging copies), we are able to find the perfect solution for optical masks, apertures, reticles and calibration plates.
