CO₂ Laser Optics
Complete Range – From Rear Mirrors to Focusing Lenses
At LMI AB, we offer a comprehensive selection of CO₂ laser optics, including:
Focusing lenses
Parabolic mirrors
Curved mirrors
Collimators
Reflective phase retarders
Rear mirrors
Output couplers
Protective windows / exit windows
We work with world-leading suppliers such as II-VI (Two Six) Infrared, who account for over 80% of the global market in CO₂ laser optics. We also supply beam delivery optics and protective glass for other laser types, including fiber lasers.
Lens Types We Offer
Our lens range covers everything from precision cutting to high-power applications:
Cut lenses – for industrial cutting
MP-5 low absorption lenses – ideal for lasers > 4 kW
Aspheric lenses
Cylindrical lenses
Meniscus lenses – industry standard
Plano-convex lenses (PoCx)
Cleaning & Handling of CO₂ Optics
Proper handling and cleaning is essential for maximizing optic lifespan.
See our step-by-step ZnSe lens cleaning guide (in English) for best practices.
💡 Quick tip for ZnSe cleaning:
Start with 20% acetic acid (diluted with water)
Finish with chemically pure acetone (red label)
Both products are available in well-stocked supermarkets – or directly from us.
Experiencing poor cutting results?
If your cutting quality is affected, don’t hesitate to contact us.
As an LMI AB customer, you receive free diagnostics and expert advice.
With the help of II-VI’s analysis tools, we can determine if the issue lies in the optics or deeper in the laser system.
Mirrors – Resonator Optics & Beam Guidance
Mirrors are used both in the resonator cavity and to guide the laser beam toward the cutting head.
They come in two main types:
Fully reflective mirrors
Partially reflective output couplers
A CO₂ laser resonator typically includes a rear mirror and a partially transmitting output coupler. The output coupler allows a small portion of the beam to exit, while reflecting the rest to maintain high energy within the cavity.
