Hello Everyone I need your help ASAP! I am doing a STEM show at a local grade school this Friday with my small 5.5w 445nm Laser and need OD4+ Acrylic sheets ( at least 3 12" x 12" x 3/16") I have been looking all over the web but can not find what I need. If you have any please let me know, I have little to no money for this (sorry!!) but working on a School budget Thanks
Best place would be 250nm to 520nm Laser Shielding – 12″ x 12″ | J Tech Photonics, Inc. However, and note this not officially tested, so you need weigh up your own safety before doing this: One of the community members over on the LaserWeb community did some testing on using normal acrylic, using a diode and a laser power meter: Read his writeup over here https://plus.google.com/+KurtMeister/posts/1vMjpwKexcr
Peter Thanks, I looked but the shipping cost is just pennies cheaper the cost of the sheets ($68.90 cost, shipping 68.83 shipping cost) Again thanks for the help
did you see the second paragraph with the link to a google+ post of someone NOT using Jtech filters. Cheap acrylic, tested.
