About this item

  • Material: Gold-Plated Silicon
  • Diameter: 38.1mm/1.5"; Thickness: 5mm/0.2"; Shape: Plane;Transmittance: >99.2%
  • The biggest advantage of Si mirror is it has high damage threshold. So it can be used in some high power laser systems such as co2 laser machines.
  • Si mirror has high reflectance and low flatness. Using the high quality surface coating will protect the layer of Silicon not to damage, and increases the Silicon layer reflection efficiency.
  • It can be applied to laser machine of higher power between 40W-400W.

Quite the step up over the factory lense. I can get the same quality cut with almost half the power.

Easy enough to install, they definitely improved the quality of the cut I was getting.

These lenses are garbage. I put one in my Aeon Mira 9 90w and it melted within minutes. I would give it 0 stars if I could.

well worth the money or should I say it was a small price to pay for a better-quality engraving and cutting.

Tested on a 250 W CO2 laser (3 mm diameter) at max power for 10 minutes or so. Mirror heated up a bit, but no more than another gold mirror in the beampath which cost 25 times more (from Research grade supplier). Second product from this supplier I’ve tried. Slightly lower performance (mirror has a slight bevel to it, see photo) but price is right. I wouldn't do anything silly like touch the gold coating or try to clean it, so maybe not the best for dirty environment.

These were an exact fit for my laser machine. They are better than the ones that came on the machine.

A notable improvement over my stock mirrors. Faster and deeper cuts, plus I was able to ditch the plastic mounting rings - money well spent.

Good mirrors. I bought a 3 pack and the plastic case had foam liner and each mirror was nicely wrapped in protective fine lens paper and then individually sealed in its own foil packet.
