Processes & Skills : Thin-film coatings

Microcertec is extending its range of products through a partnership with the company Kerdry specialist of optical and metallic thin-film coatings.

Kerdry develops and make high-precision, high-performance and customised thin-film coatings for the following industries :

  • Aerospace
  • Defence
  • Instrumentation
  • Medical
  • Optical
  • Optoelectronics
  • Telecommunication
  • Luxury


Kerdry operates solely in clean-room environment  to make its thin-film customised coatings from prototype to production quantities.


  • Au, Ag, Al, Ti, Ni, Cr, NiCr, Pt, Cu
  • Deposition techniques : electron beam & cathode sputtering
  • Applications : mirrors, brazing pads, electrical conductors
  • Thicknesses ranging from 20 nm to 5 µm depending on the deposited material


  • Ion-assisted electron beam
  • Anti-reflective coatings, mirrors, dichroic filters, custom-made filters
  • In-situ measurement


  • Standard process : dry & wet photolithography
  • Lift-off process : localised deposition
  • Precision : within one micrometer

ITO COATING - Indium Tin Oxide

  • Transparent and electricaly conductive coating



Based upon its expertise in both optical and metal thin-film depositon on all substrate types, KERDRY is capable of combining both types of coatings on the same substrate hence offering multiple functions on the same carrier.
