Default Low cost sheet semi-transparent protection sheet

Hello,
I would like to know if there is a low-cost semi-transparent laser protection sheet to use as a window for a chamber of a laser engraving machine i'm building.
Actually i'm using safety glasses, buy maybe i can build a safety box, like the pro laser cutter has.
My laser engraver has a 100/150mW red laser.
Thank you!

There was a place you could buy large panes of the material goggles are made from. That would be ideal but it's not cheap :/

A better than nothing solution would be to use multiple sheets some blue cellophane, but that's not entirely safe.

150mW is quite low power. you'll be fine with something like this:

.125" x 24" x 48" 2092 Dark Green Plexiglass Acrylic Sheet Paper Masked
