i found a wide beam red laser on ebay but i haven't made 20 posts yet so i can't post a link.
the dot diameter is 16mm, and it's 130mw. it's a 660nm laser.

if you want to find it, try searching

"1pc 3.6-4.2V 660nm 130mW Red Laser Module Dot Thick Beam Bar Stage Light"

on ebay.

Not possible, especially at that power.

There is a reason focusing mechanisms and technology exists.

That's 200mm². A pupil maxes out at 8mm, or 50mm². Therefore worst case is you're exposed to 30mW. This is indeed not eye safe, just eye safer than the alternative.

IMHO
no laser is eye safe--period.

Leave eyes and lasers to the eye surgeons.
