Coating services

Thin-film coating,
on your optics or ours.

Precision coating for infrared and visible substrates, designed for medical devices and industrial laser applications — with emphasis on performance, repeatability and qualification support.

Coating capabilities.

AR @ 10.6 µm

Anti-reflective coatings optimised for the CO₂ line. The standard specification for focusing lenses and output windows in industrial laser systems.

  • Transmission≥ 99.4% / surface
  • Reflectance≤ 0.2% / surface

Broadband IR · 2 – 12 µm

Wide-window designs for thermal imaging, spectroscopy and multi-source systems where one optic has to work across the whole MWIR and LWIR range.

  • Range2 – 12 µm
  • SubstratesGe · ZnSe · ZnS · AMTIR

Dual-band · IR + visible

Simultaneous infrared performance and a visible alignment channel through the same element — no separate alignment path required in the instrument.

  • Typical useAlignment through optic
  • SubstratesZnSe · ZnS

High-reflective & custom

HR coatings for cavity and turning mirrors, plus custom wavelength and angle-of-incidence designs when a catalogue curve will not do.

  • Custom AOIOn request

Performance

Values below are typical for AR designs at the design wavelength. Your specific curve is verified spectrophotometrically and supplied with the shipment.

  • Transmission≥ 99.4% per surface
  • Reflectance≤ 0.2% per surface
  • Absorption≤ 0.2%
  • LIDT (CO₂ CW)~15 – 25 kW/cm²
Witness samples are available for coating validation, first article inspection and qualification packages.

Coating-only service

Send us your uncoated optics.

We accept finished, uncoated optics for coating. Every incoming part is inspected before it enters the chamber — only qualified parts proceed, and we tell you exactly why anything is held.
