Exactly what I needed to replace the mirrors in my laser

Andre Rocha

Works great!!! Great quality arrived quickly as I needed this to complete a job. I would highly recommend this lens!

ibrahim malave

I purchased this lens to upgrade the stock lens on my K40. After doing a ramp test and setting the z-bed to the proper focal length, the difference is noticeable.

I was able to produce a beam of about .3mm even with the stock lens, and the Cloudray lens hit that mark as well. What improved greatly, though, was the consistency of beam width and cutting depth across the entire work area.

I can now use the entire workpiece in one run as I no longer experience blurry lines or insufficient cuts in the areas farthest from the home position. I've had a lot less frustration and wasted material since installing this lens.

In my opinion this is definitely a worthwhile purchase!

Ian Webb

These were the perfect upgrade to my stock K40 co2 laser. Received the product when stated by seller and in the condition it was advertised. Will buy from again.

John Rallo

If you have a K40(Chinese) laser cutter and happen to crack your focal lens, that's a good and quick replacement. The quality is the same as the original lens that came out of the box.
