Zinc Selenide (ZnSe) Optical Windows | 45° AOI, AR‑Coated, for 10.6μm Industrial Lasers

The WZ line covers standard diameters from 12.7 mm to 180 mm and thicknesses from 2.0 mm to 6.0 mm (models WZ‑0.5‑2 to WZ‑180‑6). These windows serve as protective barriers for CO₂ laser cutting heads, beam transfer systems, and optical enclosures, effectively keeping internal optics clean while preserving high 10.6‑μm transmittance.

Adding a dual‑band AR coating is highly advised—it can reduce per‑surface reflectance to <0.2% at 10.6 μm, improving output and lowering thermal lensing. We also offer custom coatings and sizes on request.

From small 1.5″ heads to large 180‑mm beam‑shaping setups, the WZ series ensures stable performance, ruggedness, and quick shipping. Rely on our precision ZnSe optics to extend the life of your CO₂ laser.
