250nm to 520nm Laser Shielding Material
This is a must for your new laser build! Protect the area around your machine and everyone’s eyes from stray laser radiation reflections. This material is optical grade semi-transparent acrylic material that has been tested with our 405nm and 445nm lasers to show an OD of 3+. Sheets are sold in 11 7/8″ x 11 7/8″ sizes. Easily cut with saw or router to desired size for your machine. Each piece comes with “Warning – Never Look Directly into a Laser Beam – Laser in Use”, “OD 3+ @445nm”, sticker for safety.
Be safe and not only wear safety goggles, but enclose your working area of your laser upgrade machine!

(Note: Doubling up of shieling pieces does not increase the OD value)
Laser marking circuit boards with shield. Notice the spot is very attenuated.
Same laser marking without shielding. Quite a difference with laser reflection.
