CloudrayCO2 Laser Lens 20mm Laser Mirror CO2 Laser Focal Lens CO2 Focus Lens,PVD ZnSe for CO2 Laser Engraving Cutting Machine,Laser Cutter 30W-100W,Dia 20mm FL127mm

The lens works very good, cheap and good, i use it at least 6 hours a day, 6 days at week,

No expert, but after I coupled this lens with the Light Object laser head it burned through 1/4 Birch in two passes at 20mm/s @15mA.Which is way better than the stock set up.

Awesome so far, Seems better than OEM and way less expensive. When needed I will purchase one for my PS48

This lens immediately improved the quality of my cuts. Not sure about longevity yet, but at this print I can buy almost a dozen before reaching the OEM cost from Full Spectrum.

Product arrived in 2 days. Made a big difference in the engraving

Quality optics. My 60 watt laser will now cut 3/8 hardwood without scorching it.

works good

Worked better than the original

Brilliant lense , have to say my 80w laser is cutting better than the stock included lense .

Did not last a day protective coating came off only on 30% power

Big difference from stock K40 , Highly recommended

Perfect in every way

Ho acquistato questa lente al costo di 27 euro pensando di averne dei benefici rispetto alla cinesata che ho montato sulla mia macchina. Purtroppo la qualita' è identica e sono arrivato alla conclusione che non sempre il costo è proporzionato alla qualita'
