This ( ebay.com/itm/132958757353 ) is basically what I'm looking for but I have no idea what the actual spec of something like this might be. Does anyone have any leads on a reputable source for something like this? Could be something else too, my essential need is that I can add my own power...

Should mention the distance the laser needs to cover is only about 20 yards.

I'm trying to photograph a line drawn with a laser during a dark overcast day. My basic understanding is that 555nm is brightest in daylight and 100mw+ is strong enough to start a fire. So, I want something that is less than 100mw. Am I on the right track? Is this simply not possible with this...

Thank you, this makes sense.

LOL, I actually bought it several months before the outbreak, but who knows what else could be on it...

The idea is to draw a line across the canyon wall at a distance of no more than 100 yards. I've included an image of the goggles which state printed on them: "For viewing of diffuse laser light only. OD 7 @ 190-380nm, 3-4 @ 740-785nm, 5+ @ 785-1063nm, 7+ @ 4064nm, 5 @ 10600nm"

Noob here. I'm looking to create art utilizing a laser in the landscape. First and foremost I want to be safe for myself, others and the environment. I have already purchased a laser and safety glasses but I realized I don't know if I am being safe. I have chosen not to power on the laser until...
