TEN-HIGH Diam 20mm Focal Lens for CO2 Laser Cutting,FL: 2" (2"/50.8mm)

My old lens developed a crack. I installed this one, and I was able to cut faster than ever. I don't know if this is just better than my old lens, or my old lens was perhaps getting old. I bought the laser cutter used and I do not know the hours on the old lens. But this one works very well and I am pleased with its performance.

I have much more expensive lenses but these are quite decent for the price. They focus a nice tight beam and last a good long time.

Leicht zu Reinigen die Krümmung ist sehr gut bei meinem Laser 50W funktioniertes sehr GUT und das Ergebnis kann sich sehen lassen

These are good lenses - they cut well, as expected.
