Default laser beam stop

Is a brick painted matt black(spray paint,non reflective) a usable beam stop for a 100mw 445nm laser, so thatit can be viewed without safety glasses

Yes, the uneven surface of a brick coupled with matte black BBQ/high thermal paint
is ideal for that.

For even less light escaping from the side (180 degree emission from the bricks face) you should consider using a dark pipe with your brick at the end of said pipe, and shinning the laser through the pipe before it gets terminated on the brick.

This is good for higher visability/power, but at 100mw of 445nm, its very little to worry about.

Default Re: laser beam stop

That will work. What GBD mentioned will also make it safer. I made my beam stop by spray painting steel wool with BBQ paint and then stuffing it into a pipe that is also spray painted. The steel wool works extremely well.

Default Re: laser beam stop

you can view the dot of 100mw safely, just don't stare at it for 5 seconds+ and don't have it 2 inches from your face
