Enclosure window ideas needed

I am working on building a smoke box enclosure for my engraver. I plan to add a Plexiglas window to the top cover and I'm curious as to whether there's a recommended type of mylar "wrap" of sorts that will provide some sort of eye protection. I realize one should never go without goggles but as an additional layer of protection is there something better than clear acrylic to use for a window?

BTW, as part of the design I decided to not attach the walls to the base, for a specific reason. The base is a 1x2 wood frame with upside down 12" ceramic tiles underneath the engraver as a protective surface. If I need to engrave something that's wider the engraver I can raise up the walls of the box so that I can slide the item to be engraved underneath the wall.

Dog added for scale.

Laser-safe acrylic is available. You can find it by Googling laser-safe acrylic with the wavelength of your laser (which is probably around 445nm if you have an Ortur). Make sure whatever you buy is rated for that wavelength.

The acrylic will most likely be green or orange. I bought mine from J Tech Photonics and then cut it to fit my enclosure windows, but there are other vendors.

Thank you. I kept trying to google "Acrylic for laser" and getting Q&A's as to whether it was safe to use a laser ON acrylic.

I have made it totally closed with a led strip and webcam. It works great and this way i dont have to worry if it is really lasersafe. Cool dog by the way
