  • Works great for engraving metal.
Color: 70x70mm FL100mm
This lens works great on stainless steel, delivering deep, beautiful engravings. For those wondering, a fiber laser uses galvo mirrors to steer a highly focused beam, generating intense heat at the work surface. This concentrated heat is powerful enough for engraving, marking, or even cutting metal -without direct contact or the use of a blade- and this lens is designed specifically for the job. ... show more

  • Great
Color: 70x70mm FL100mm
The XUNKUANER F-Theta Lens is a reliable choice for fiber laser marking and engraving systems. With a 70x70mm marking area and 100mm focal length, it delivers sharp, consistent results. The lens is well-built with clear optics, and the M85x1 thread makes it easy to install on most 1064nm galvo systems. It performs well in maintaining focus and precision across the full field. The lens is durable and provides excellent clarity, especially for detailed engraving tasks. However, it’s best suited for small to medium work areas. Overall, a solid upgrade for those seeking enhanced accuracy and performance in laser applications. ... show more

  • Great Galvo Lens
Color: 110x110mm FL160mm
This is great. Works well, fantastic price, and it is made with the same weight and solid construction as a much pricier option. Definitely recommend.

  • It seems to work fine.
Color: 110x110mm FL160mm
The lens for my galvo laser and seems to work perfectly. I use a cloudray lens of the same size so i was able to quickly swap them to test and they both engraved exactly the same on a metal card. The only issue I ran onto was that even though they were the same lens size they are not the exact same physical size which means that it had to manually adjust the focus. Something else to add is that when you are changing the lens size you also have to adjust the settings on your marking software to fit the new dimensions or you'll also have issues. The one thing I didn’t like about this lens is that it doesn’t have a protective lens at the bottom like cloudrey has, cloudrey has a third lens at the bottom that you can easily remove to clean. This lens doesn't have one so the bottom lens is exposed so you have to be extra careful with it. Other than that they both worked exactly the same. ... show more
