CNCOLETECH CO2 Laser Lens Dia:15mm FL:2 or 50.8mm Laser Mirror CVD ZnSe Focus Focal Lens for CO2 Laser Engraving Cutting Engraver/Cutter 40W-200W

If you have a K40(Chinese) laser cutter and happen to crack your focal lens, thats a good and quick replacement. The quality is the same as the original lens that came out of the box.

Can’t beat the price point. Lens works great.

Confezionamento top. Lenti OK!!!

Excellent. Huge difference between my stock lens and this one.

Better replacement for the boss laser. Working great better than the original one that came with the laser.

This was a great replacement Focus lens for my 40 watt unit. I would buy it again

El producto es bueno ,pero la empresa de transporte nefasta y no es la primera vez.

used these 4 100s of hours on a 50 wt , work great

Not a good discription

Would definitely buy again!
