  • Fiber lasers friend
Size: 70x70mm FL100mm
This has become my go-to fiber laser lens brand. Always high quality, durable and perfect focus.

  • Great lens for OMtech fiber lens

  • Watch how your tighten it
Size: 70x70mm FL100mm
The good: Love the lens. I originally had an f290 for big projects but when I need the power density for deep etching or etching copper PCB, this 100mm fits the bill. Perfect fit on my JPT. The bad: I must have tightened it a little too tight although, I don't believe so. This lens gauled. When I went to switch back to my F290, this lens would not unscrew. I tried almost everything to loosen this thing up. This seems to be unique to Cloudray F-theta lenses as I have seen other user having this trouble. Not sure if it's the anodize dye they use or what. I finally unscrewed the entire lens receiver from the galvo head and used a syringe type oil applicator and dripped oil on the inside taper of the lens to let it soak into the threads and also so I could keep oil away from the optics. Trust me, this was a last resort. After soaking for about an hour, the lens loosened up and I had a time trying to clean up the oil while trying to keep the optics spotless. After another hour, 20 or so paper towels, and a half a bottle of 99% IPA, the oil was cleaned off lens assembly and the lens receiver. Either use an anti-seize thread treatment or tighten these lenses feather tight. Mine gauled like you wouldn't believe. That's the only reason I am giving this 4 stars instead of 5. ... show more

  • Great Lens
Size: 70x70mm FL100mm
Works perfectly, very little distortion and was easy to set up in Ezcad2. Using this on a 30 watt no-name fiber laser. The increased power over my 150 x 150 lens is perfect for smaller items like jewelry and much easier to cut metal using this lens.
