just wondering do you need a special mirrored acrylic for cutting in a laser cutter?
Logic tells me it will reflect the laser beam if reflective side up
tried cutting some with reflective side down but it damages the reflective material and doesn't look good
Any advice

Re: mirrored acrylic
Hiya Graham,
Mirrors are incapable or reflecting light in the spectrum that a CO2 laser produces Mirrors by their nature reflect photons of certain wavelengths (visible light) when it comes to laser radiation mirrors react in a much different way.coupled with this the beam divergance upon striking the reflective surface is such that it scatters quickly.
Any kind of mirrored perspex / acrylic is fine to cut from the reflective side.
hope that helps
best wishes
Dave

Re: mirrored acrylic
very scientific! - must admit wasn't the answer i was expecting! Thanks though much appreciated- will now go cut some mirror!
Re: mirrored acrylic
I better clarify Graham,
Acrylic mirror doesn't reflect laser radiation, Miniscus glass mirror DOES!
I just suddenly had this vision of you trying to engrave or cut glass mirror
In short acrylic / perspex mirror = fine
Glass Mirror = Bad
