I bought the nozzle/lens set to install on a Chinese 100-watt laser from HL Laser. The nozzle didn't fit the dinky little head included with the machine so I upgraded to a Cloudray laser head. These two pieces together (nozzle and laser head) make my machine many times as flexible as it was stock. I can use 18mm or 20mm lenses and changing lenses is a snap.
This compound lens set is the real deal. I'm able to cut very fine well-defined lines at twice the speed I was able to before with the stock lens.
WARNING: I ruined the lower lens in this set by cutting Corian. The mineral content in Corian sparks on content with the laser. The focal length of the compound set is so small (and my air assist is so weak) that the sparks shot up into the nozzle and burned and pitted the lower lens. Lesson learned. For materials that are prone to sparks/flaming use a longer focal length lens to keep the lens out of harms way and/or increase your air assist pressure.
Overall an excellent purchase for the price.

Nice lense system. You have to insert both lenses at the same time in the correct order and orientation to get a good result. Be sure not to overtighten the lensring. This would have negative effect on beam transmission ability through ZnSe material! Only tighten the ring very carefully.

It came quickly. Corresponds to the description. In the nozzle is suitable. True, I did not understand, two lenses simultaneously insert or alternately.

My previous NO4 was out of use, so I came to Cloudray to buy a new one. I feel that the quality is great and I hope it will be a good shopping experience.

While the assembly instructions took a minute to comprehend, we got it put together. The results of resolution are fantastic, if it stays in focus. We are getting lots of horizontal lines or variations in the burn. Still perfecting its use, we do like the good parts we have gotten.

haven't used it yet but I'm sure it will be fine

Item is very good for detailed engraving. Beware when using for cutting. Acrylic is ok but wood can catch fire. The detailing in the engraving though....wow
