hey all, Im a noob, what kind of lens would you use to focus the beam, this is one of those "i don't have it yet but i need to know" questions, so thing number one, what kind of lens you use? is it the convex lens that is plain on the other side?? that's the only one that makes sense to use, and another question, if focusing u can create a 1mm wide beam for example 4 feet away, how would you focus it to "infinity" and is it possible, what i mean by infinity is like when u use binoculars, when u focus them on a far object you can look at objects that are even further but they will not need focusing anymore... so what is the max possible viewing distance i could get from a 1W 445nm, and handheld 473nm of the max power i could build/buy for under $250 that will be discussed separately.
