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.

- Reflectance≤ 0.2% per surface
- Absorption≤ 0.2%
- LIDT (CO₂ CW)~15 – 25 kW/cm²
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.
