I got given a laser engraver. One of the cheap, no-safety-features-whatsoever ones from the usual source of such things. I've already managed to engrave the test pattern in the desk it was sitting on*. It is also extremely bright, even with the supplied protective goggles. 


So I am (quite sensibly if I do say so myself) currently building an enclosure for it. I'd like to include a window to keep an eye on things. Google has lead me to high optical density acrylic for this. However, I can't find an obvious supplier of this in NZ. Some overseas suppliers seem to suggest an orange tint, and the supplied protective googles are green. Any suggestions where I can find this?


The supplied laser specifications are 450nm wavelength and 7W power (this one).


The enclosure I am building is 450mm square, so the window can be that size or smaller. Depending on price, one easy option is to make the top 450mm square, but I can also inset something like a 300mm square window if that is a standard size.




* It was through the cardboard it was supposed to be engraving, so more powerful than I expected. And now I have a permanent reminder not to be stupid with it.

Have you tried searching for acrylic sheet? There's several places that will cut to size what you need, but you may have to contact them regarding a specific product.
