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.
Attention:
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.

How to Determine Focal Length
Focal length is the distance between the lens and the workpiece(material being cut or engraved).Before replace or install the lens, please confirm the diameter and focal length firstly. You may confirm the focal length of your lens according to the following pic.

Tips
For engraving, we recommend using a laser lens with a focal length of 38.1mm or 50.8mm. If you're planning to cut, we suggest using a laser lens with a focal length of 63.5mm, 76.2mm, 101.6mm, or 127mm.
Schematic Diagram
It is recommended to use convex upward, flat or concave facing the engraving or cutting material. Usually one co2 laser engraver needs 1 pcs focus lens and 3 pcs reflective mirrors.
Application
Usually one co2 laser engraver needs 1 pcs focus lens and 3 pcs reflective mirrors
Lens shape: 50.8mm/2 " and 63.5mm/2.5" FL are plano convex or meniscus: 127mm/5 "FL is meniscus: other FL (38.1/1.5' 76.2mm/3 "101.6mm/4") is plano convex. The above is the default shape. If you have special needs, we can customize it. Please send us message.

I use an 80W-100W max CO2 that has gone through moly mirrors and copper coated mirrors. These are solid and should have been my first choice. Well worth the money.
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.
Excellent product would seem to be durable. Excellent lens for engraving and also cutting.
