    • New at laser cutting engraving
Size: Dia:20mm FL:1.5"/38.1mm
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!!! ... show more

    • Worth the cost

I bought a Chinese Ebay laser that came with a 1.5" lens. It wasn't very good, so upgraded with this lens and power output is at least 1/3rd stronger. The lens is clear, no blemishes and packed well. Not only do I get a better focused cut, it also uses less energy so the tube will last longer.

    • Great product
Size: Dia:18mm FL:1.5"/38.1mm
Very well packaged. I bought the 18mm 1.5" lense. Came very clean not cloudy at all. Getting excellent fine lines with a perfect job at grayscale photos. Very impressed. Wish I could go to the 1" lense but with my current setup the lense carriage wouldnt allow it.

    • Good price/value. Good for shape/size. Great packaging.

I had a gravity-assisted failure of my original lens. This replacement was well packed (2 layers of padding, plus the foam padding of the hard-case it came in. Drop-in replacement that "just worked' and the beam quality is as least as good as the original.
