Blocking 406nm laser

Postby heyarn » Wed Mar 11, 2015 5:19 pm

Hi Folks,

I heard that we can just get some green translucent acrylic to block the UV. I'm thinking of ordering some 6mm acrylic, then bending it, but have no clue as to whether or not this is true, and if it is, what tint of green I should use. Can anyone point me in the right direction?

Not Green, you want orange (amber) or red. Look for Acrylic color #2422 (Amber Translucent) 3mm is plenty and easier to work with.

Weird, because I bought protective laser glasses from aliexpress for specifically 405nm.. it was green.. was I tricked?

would 3mm thickness suffice? Or should I go with 6mm?

Thanks!
