I want to make a 2.5w 445nm blue laser engraving enclosure, in addition to wearing googles.
The laser enclosures are expensive and small.
What If I buy 4mm thick orange acrylic, and test it with a LPM?
I can test the reflection, as well as a direct shot through the acrylic. It would be hard...
I am so glad to find this forum.
I unfortunately found this forum after I ordered some $5 laser googles from banggood
I reorder better ones from survival laser.
