FreeMascot OD 6+ 9000nm-11000nm / 10600nm Wavelength CO2 Laser Safety Glasses

Work well and last a long time without getting scratched up

I can still see so must be working. I don't know of any other way to verify if in fact the glasses are protecting my eye sight.

I have a pair of FreeMascot glasses for my co2 and diode laser. I still have my eyesight. The glasses for my diode are a different spectrum. I have been using them for a while now.

They must think Americans are giants. I have a rather large face and a size large head and these things make me look like a baby in big people glasses. They are better than the last free mascot style, but still giant.

Perfectos para trabajar, buen material y diseño, la visión es buena ya que son casi transparentes

If you have a CO2 laser these are a must have. I use them whenever my laser is turned on even when the lid is closed. They fit well over my eye glasses. You only have one pair of eyes.

Excellent quality, always know your wavelength that you want filtered out because this is no one pair of glasses for all. Also, test them - try to burn through a small spot. If it goes through don't use!!!!

They seem to work. They fit well. I haven't tested shining the laser through them to see if the beam is blocked on my K40 so I can't guarantee they're not not just plain plastic but I trust the vendor.
