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

Well done Cloudray! Good value for the money
Size: 70x70mm FL100mm
I purchased this lens as my original lens ordered with my fiber laser was a focal length 210mm 150x150mm workspace, which is great for larger , less detailed work, but not so great for deeper engraving or ultra fine detail. I use Lightburn for Mac, which is, in my opinion, the best engraving software. There are plenty of tutorials on Lightburn’s YouTube channel detailing calibrating each lens. It should be noted every time you get a new lens you will have to calibrate, but it’s relatively straight forward. Once this new lens was calibrated and I ran a couple test engravings on both aluminum and steel, i was very impressed with the results. I look forward to doing some firearm engraving soon and will add pics once done.

Great product from a great company!
Size: 175x175mm FL254mm
I am so happy I purchased this lens. My original laser machine came with the Cloudray F-Theta 300x300, having this new lense 175x175 has opened up more opportunities for less more direct power with smaller products like knife blades. The product is well built and installed in seconds on my exsisting machine. I will be buying more of these in a variety if sizes from the Cloudray Amazon store. It shipped fast which was appreciated!

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.

It works.
Size: 250x250mm FL380mm
Upgraded from my 110 lens to hit bigger items. Came well packed and was easy to install. Definitely recommend especially if you want to engrave full tumblers.

No customer support?
Size: 250x250mm FL380mm
I bought three of these lens in different scan field sizes. I subsequently sent Cloudray an email to customer support and I received no repsonse. If you are willing to buy these lens without customer support, it may be a good choice. I personally expect a response to a clearly written question via email.

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.
