### ⭐⭐⭐⭐⭐ Great lens
*by S***M on September 7, 2025*

### ⭐⭐⭐⭐⭐ Instant power up!
*by S***I on February 17, 2020*

I bought the air assist that allows use of 18mm lens, so I gave this lens a shot, the price is decent and the spec. Looked not much different than the more expensive brands. Got it today with also the mirrors from The same sellers. So I installed it in my K40 laser engraver replacing the stock laser head with the new LO head with air assist with the new lens and mirror. InScrewed up the alignment at first, but after making some adjustment and set power to 10% and test it on a cardboard. BAM! It cut thru the cardboard in one pass while before it only leaves a line! Who knows, maybe the alignment was off before, but I definitely think the lens made a difference, for the quality of the coating on both the lens and mirror are better than the stock. It is a worthy upgrade, now marking on stainless turns out great, really helps serve the purpose of getting the K40 in the first place.
