Laser safe acrylic for enclosure viewing window

Hi. Does anybody have any suggestions for types of acrylic I could use for a viewing window? Just building an enclosure and would like to see the laser at work. I’ll be using the E80. I’ve seen some orange laser safe acrylic 12”x12” but just wondered if I could use something else?
New to all this, thanks in advance!

Anybody? :open_mouth:

You can use red or green translucent acrylic

Any type? I’m reading it has to be ‘laser safe’ and that stuff costs a lot of money! Sorry to keep asking, but I don’t want to risk it.
Has anyone on the forum used a certain type of acrylic you mention?





Thank you Jim, much appreciated! :+1:
