The MCWlaser Lens for CO2 Laser 10600nm 10.6um - the perfect choice for precision engraving and cutting.

1.Hight quality PVD Znse crystal material
2.Our double-sided solid coating ensures extended durability and wiping resistance, while our precision slicing, polishing, and grinding processes guarantee excellent optical properties and high working efficiency.
3.With high-temperature laser resistance and a laser transmittance of up to 99.8%, our lens is the best option for your laser applications.

To avoid lens breakage, follow these tips:
(1) Ensure proper air cooling to prevent overheating and cracking.
(2) Watch out for condensation water drops in the lens barrel, as they may cause breakage.
(3) Keep the lens clean and free of debris from the cut or engrave material to avoid uneven heating over time, which may cause breakage. Clean with a cotton ball dipped in absolute alcohol or acetone.
(4) When adjusting the light path, ensure that the laser does not accidentally hit the edge of the lens or the junction of the lens barrel, as this may cause breakage.


Note: Thickness Tolerance: ±0.2mm


PVD (Physical Vapor Deposition) ZnSe (Zinc Selenide) laser lenses are commonly used in laser systems for various applications due to their excellent optical properties. ZnSe is a popular choice for laser optics because it has a high transmittance in the infrared spectrum, particularly around the CO2 laser wavelength (10.6 µm).

Laser Cutting: ZnSe lenses are widely used in CO2 laser cutting machines to focus the laser beam onto the material being cut. They help achieve high precision and clean cuts, especially in materials like acrylic, wood, and certain metals.

Laser Engraving: In laser engraving systems, ZnSe lenses are used to focus the laser beam onto the surface of the material to create detailed and precise engravings. They are essential for achieving high-resolution images and text on various materials.

Material Processing: ZnSe lenses are employed in laser systems used for marking, drilling, welding, and other material processing applications. They play a crucial role in directing and focusing the laser beam to achieve the desired processing results.

Claire Hawker

I've ordered this lens several times and it works great. Gone are the days that I need to lose sleep about ruining a $100 lens when I can just buy a few of these and have some as backup. I notice no difference in cut/engraving quality compared with a more expensive lens.

Cameron Coleman

Excellent product would seem to be durable. Excellent lens for engraving and also cutting.
