I had a quick question about green line generators. How powerful do they need to be to have a visible 'beam' I have a project idea but it requires a green line generator that has a visible 'beam' or plane. Thanks! I'm thinking it will be about 2-3in long/wide.

It all depends on the particulate in the air... in pure clean air you would
not see a 500mW beam and in a fog filled room you could see a 5mW
beam...:cool:

Average inside, and average night. Like....not completely dusty, but some normal inside dust. You know what I mean? In comparison to a laser pointer, how much more or less is the visibility of a line generator?
