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 4+. Sheets are sold in 11 7/8″ x 11 7/8″ sizes. Easily cut with saw or router to desired size for your machine. You can even cut it with your new 2.8W laser kit and engrave your logo or warning signs on it as well. Each piece comes with “Warning – Laser in Use”, “OD 4+ @445nm”, and “Warning – Never Look Directly into a Laser Beam” stickers for safety.
Be safe and not only wear safety goggles, but enclose your working area of your laser upgrade machine!
