We were just hitting our busy season in our shop ...

We were just hitting our busy season in our shop when the lens cracked in our laser. Since we were still new to using laser we didn't even know that was an option to have happened! We took a chance and ordered 2 so we wouldn't have downtime again, and did rush shipping. Our order showed up fast and they worked perfectly! This saved our shop right at the holiday rush!

Good lens

I'm using this lens with a 1000x50mm 45w tube and it works very well. Use your air assist and keep the lens clean and it should last you many hours of use.

Universal Laser worked well

I have a Universal ULS6.60 laser. I used acetone to get the old lens out. Put this one is the same direction with some super glue. It cuts better than I ever remember. Couldn't be happier.

As advertised, works great.

Have a boss laser and it has a couple cloudy spots on the lens. While it still cuts ok, wanted a backup that did not cost me $220. When I got the new lens in, it was well wrapped and packaged. Gave it a quick clean, installed it and it cut like a champ.

great lens for the air assist nozzle

Good price and quality

Good price works as expected. I saw a few posts where people have expressed fogging, which is true but this lens needs additional care specifically of you have used it for longer duration. Ensure air circulation through laser nozzle during cut.

This lens worked great. Just keep it clean!

I used this lens to replace a badly damaged one in a focusing assembly in an admittedly horrible laser cutter. The lens did the job it was asked to do and turned my horrible machine in to one that was now barely tolerable. I got rid of the machine and kept the lens.

It works..

Worked perfectly in my blue eBay laser.
