CVD II-VI ZnSe Focus Lens 20mm CO2 Laser Lens FL:76.2mm/3" for CO2 Laser Engraving Cutting Engraver/Cutter 40W-200W

Was literally burning through lenses left and right. Contacted manufacturer and they pointed me towards this lens. Such a difference in quality and performance when you have the right lens! If you have a CO2 Laser, this is the focal lens you need!My machine manufacturer wouldn't list the specs for replacement lenses because they want to sell to you after market parts. (Not mentioning names, but rhymes with Jonport. Due to other quality issues with this machine I vowed to NEVER spend another dime with that company. So I needed an outside source for replacement parts) Thanks!

I bought a Laguna Laser. With no previous knowledge of such I went ahead blindly. I've learned a lot since it first arrived but, to be honest, Laguna isn't someone I would recommend as far as sales. They lie. It's just that simple. They had no idea of when they would ship my purchase. I actually waited over six months before it arrived. But that's an entire other story. I wanted spare parts. I asked for three months for a replacement nozzle and when it finally came it was the wrong part. So I needed the parts and the Lens was definitely some thing I needed. I tried this one because I hoped it would fit and it was perfect. I installed it and that was all and it's been working exactly as it should and I am grateful to have been able to buy it through Amazon and have it delivery within 2 days!!!

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.

I have purchased multiple times and will continue to do so as I need replacements for this consumable.

I have some unique glasses that are curved and tapered and I didn't think the standard 2" focal length lense on my laser machine would handle the varying focus depth.I started with a ramp test on this new 3" FL from cnole tech and found the ideal FL was 70 mm from work surface to the bottom flat face of the lense with a great focus in 2mm either direction a total of 4mm variance.I'm impressed with the ability to remain a relatively fine point focus at this FL. The Lense appears to be of high quality and was delivered scratch free with a perfect polish.

I managed to drop my original OEM lens while cleaning it...don't do that as they are very brittle.OMTech focus lenses were out of stock so I took a chance and just ordered from Amazon. The new lens worked but it seemed like my laser settings needed to change. It needed different settings to properly engrave powder coated stainless steel tumblers from what I had historically used. Not better or worse, just different. I only ran a grid test with power/speed to find a better setting. I never did try a ramp test to see if it was bacause the focal length was slightly different. Overall very happy with this relatively cheap alternative to buying from OMTech.

The lens was just a bit thicker than the original ULS M-300 2.0 lens - but it still fit perfectly in the lens carrier and the extra thickness didn't extend beyond the milled portion of the carrier. Any thicker and this would have failed. Just did my first cut and engrave with it and the quality looks good. It seems to me that some 5 years ago I had purchased a similar product and it did not fit. Stocking up with a few extra of these, now that I know they fit, just to have around.

I cut the bottom out of my k40 to accommodate rollers and larger items. Being able to get the work piece away from the head has been awesome.

Muy buena calidad precio ,la mejor elección recomendado

Ottimo

Works as expected

Das wechseln der Linse ergibt ein weit besser Ergebnis. Die Linse muß richtig eingebaut werden und nicht mit den Fingern berühren. Beim Kauf auf den richtige Durchmesser achten.
