Most of the ZnSe lenses can be delivered within 1½ to 2 weeks. If you need lenses with other diameter, focal length or edge thickness, please send us your request. The max. pressure value are recommandations.

Absorption: 0.20%
± 0.03% @ 10.6 µm • Focal tolerance: < ± 0.5% (better than standard)
Surface figure: λ/40 @ 10.6 µm • Surface quality: 40/20 Scratch/Dig (laser quality, both sides)
Substrate: ZnSe, laser grade (USA)

We also offer the re-polishing of your used ZnSe lenses. Please contact us for details.


We recommend thsese ZnSe lenses for high power CO2 laser (> 4 kW) and for steel cutting:

- Longer life time and better focus point due to the low absorption
- Higher cutting speed
- Low absorption is guaranteed, even if edge thickness of the lenses is different
- Coating transmits visible light (important for adjustment light)
