Mssoomm 25mm GaAs Co2 Laser Focal Focus Lens Diam 25mm /1" Focal Length FL 63.5mm /2.5" for 100w 120w 150w 200w 250w 300w 500w 600w Watt CO2 Laser Cutter Engraver Cutting Engraving Machine

I wasn't sure if this would work well with my 130W CO2, but wanted to give it a try based on a "smaller" spot size comment in prior reviews. I like to try different lenses, and this particular one seems to have the same spot size. but the cutting depth appears to be better than the previous ZnSe I tested. Supposedly these get warmer, but at the same time are supposed to be tougher.I am happy with it, but should point out that it is not transparent like the ZnSe lenses. For someone who likes to look through from the mirror to the work in order to inspect the mirror, it is inconvenient.Overall good value.

I have a 100 watt co2 laser and this lens allows me to engrave with a small dot (about the soze that I was getting with my 38.1mm regular focal lenses). I will see how long it holds up, but based on the initial engraving quality Ia really optimistic. Because I only have 100 watt co2 laser, I wasn't sure how necessary one of these focal lenses were, but I am glad that I tried it out.

Make sure you have a powerful enough laser or this lense isn’t for you. Exactly as advertised.
