Infrared.
Specified.
Delivered.
CO2 laser lenses, infrared windows and AR coatings — manufactured and coated here (five chambers, ISO 9001). ZnSe, germanium, silicon and specified laser optics quoted to print.
Dial λ.
Read the substrate.
Drag from deep ultraviolet to long-wave infrared. Every substrate we stock lights up the moment your wavelength falls inside its transmission window — with wavenumber and photon energy, so you can check it against your source.

Ranges are approximate useful transmission windows. Cut-on and cut-off shift with grade, thickness, temperature and coating design — confirm against a grade-specific datasheet before design freeze.
From UV glass to
long-wave semiconductors.
Sourced through a qualified global network, prepared for yield, and carried with full batch and lot traceability — whichever end of the spectrum you work in.
Zinc Selenide
CVD laser grade, ≤ 80 µm inclusions. The workhorse for CO₂ optics — low absorption at 10.6 µm and a visible alignment channel.
- n @ 10.6 µm2.4028
- BandsVIS · NIR · MWIR · LWIR
Germanium
Highest index of the common IR set — compact thermal optics. Specify operating temperature; transmission falls off with heat.
- n @ 10.6 µm4.0032
- BandsMWIR · LWIR
Silicon
Low density, high thermal conductivity. Preferred for weight-sensitive MWIR windows and laser mirror substrates.
- Density2.33 g/cm³
- BandsNIR · SWIR · MWIR
Chalcogenide Glass
Moldable, athermal glass with very low dn/dT — the choice when a thermal imager must hold focus across temperature.
- n @ 10.6 µm2.5109
- BandsNIR · SWIR · MWIR · LWIR
Copper Mirrors
Diamond-turned metal mirror substrates for high-power beam delivery, where no transmissive optic would survive the load.
- Reflectance> 98% @ 10.6 µm
- CoolingWater-cooled option
UV & Visible
Fused silica, calcium and magnesium fluoride, sapphire and N-BK7 — for alignment paths, beam combiners and visible channels.

How an OEM program runs.
Repeat production is a process problem, not a parts problem. We qualify once, then hold the recipe — so the hundredth batch matches the first article.
-
Sourcing & material qualification
Grade selection, inclusion criteria and yield-optimised blank layout against your print.
-
Precision fabrication
Grinding, polishing and edging to tolerance, with in-process metrology at each station.
-
Thin-film coating
Controlled deposition with witness samples; AR, broadband, dual-band or HR designs.
-
Inspection & qualification
Interferometric figure verification and spectrophotometric T/R against the approved curve.
-
Repeat production
Locked recipe, batch traceability and inventory-based fulfilment for recurring part numbers.
We coat your optics, too.
Send finished, uncoated optics for coating-only service. Incoming inspection covers surface quality, flatness and figure, edge and chamfer condition, and coating compatibility — only qualified parts proceed.
