Review: Good for thick material - I was having trouble with my old Full Spectrum MLE30 (K40 predecessor type). I was using ot for a couple types of plastic (Acrylic mostly, but some Kydex) as well as cutting heavy 10oz dual-tanned latigo leather. My problem was that in order to cut through the material, I was ending up with severe charring at the edges of the cut and often insufficient penetration. It had sat without use for a good 12 years and my assumption at first was that the tube was just bad. I was told this happened over time. Surprisingly, the tube was just about perfect. I definitely gained a little bit of performance switching to a name brand 35w tube, but not nearly what I thought I would. When that didn't really solve the problem, I re-leveled the table again, re-aligned the mirrors for about the fourth time, cleaned everything, and was at a loss. I thought about it for a while and did a little geometry in my head, and theorized that I could improve cut depth by going to a longer focal length. Reddit seemed to confirm that this was usually what people did for this sort of thing. The solution ended up being to switch from a 2" focal length to a 3" focal length for the thicker material, where the critical focus depth ended up going from 1-2mm to about 3-4mm and really reducing the charring and improving the consistency of cutting through. It's still not perfect, but going from rough cut to finished part takes about 1/4 of the time now and results in far less cleanup and failed parts. I do have to remove the honeycomb bed to use the 3" lens, but cutting leather usually doesn't resul;t in any issues.
Review: Good quality! Amazing for tumblers with tabs for removable handles!! - I have only had my new lens for about a week and it's making a world of difference for my laser engraving business! I highly recommend this product!! Works great for tumblers with tabs for handle. UPDATE!: I have had the lens for about 10 months and the coating has started to flake off. Honestly I'm not really upset about it as it is only a $30 replacement part. Overall I am still happy with this lens!

### ⭐⭐⭐⭐⭐ Good for thick material
*by C***D on August 14, 2026*

I was having trouble with my old Full Spectrum MLE30 (K40 predecessor type).

### ⭐⭐⭐⭐⭐ Drop in replacement for Boss Laser LS1420
*by C***W on October 20, 2022*

The 20mm FL:2" is a perfect drop-in replacement for the default focus lens on the Boss LS-1420 laser. Boss wants $100 for their lens but I found that this one was much cheaper and had all the same specs. So far I've run my laser for about 10 hours engraving and cutting 1/4" solid cedar and 1/8" baltic ply and am getting sharp engraves at 385mm/s, and clean single pass cuts. Just make sure you wipe your lens down often during jobs and get a good air compressor. My original lens lasted three years before I replaced it with this due to my own negligence. I've picked up another spare just in case I forget to wipe the lens down again. Make sure to pay attention to the direction of the curve on the lens, and also make sure to wipe down all your mirrors while you're swapping out the lens. Wear gloves and only handle the sides of the lens.
