Enclose your whole machine with this GIANT piece of shielding! \u00a0This is as big as we can get a piece and still be able to ship it effectively. \u00a0It costs a bit more than our smaller pieces due to the increased packaging cost.<\/p>\n

This is a must for your new laser build! Protect the area around your machine and everyone\u2019s eyes from stray laser radiation reflections. \u00a0This material is optical grade semi-transparent acrylic material that has been tested with our 405nm and 445nm lasers to show an OD of 3+. \u00a0Sheets are sold in 23 7\/8\u2033 x 23 7\/8\u2033 sizes. \u00a0Easily cut with saw or router to desired size for your machine.\u00a0 Each piece comes with \u201cWarning \u2013 Never Look Directly into a Laser Beam – Laser in Use\u201d, \u201cOD 3+ @445nm\u201d,\u00a0 sticker for safety.<\/p>\n

Be safe and not only wear safety goggles<\/a>, but enclose your working area of your laser upgrade machine!<\/p>\n

\"Laser<\/a><\/p>\n

Laser marking circuit boards with shield. \u00a0Notice the spot is very attenuated.<\/p>\n

\"Laser<\/a><\/p>\n

Same laser marking without shielding. \u00a0Quite a difference with laser reflection.<\/p>\n
