So I've searched the forum and google and haven't found anything really with a clear answer. Is there a lens make for 445nm that produces a dot as opposed to a short line? Is there an easy way to get a dot?
Thanks peeps

You need cylindrical optics to correct the line. The optics are avaible from dr lava.
But they are for labby lasers, not pointers.

445 nm diodes are multi-mode meaning that it is the diode itself that produces the lines not the lens. On the 400mw dragon laser spartan the edges are "clipped" off to produce a better dot profile. Corrective optics can also be use to achieve a round dot, although I haven't seen anything too much on correcting it. I know (as stated above) dr.lava has some optics, but I haven't really seen it implemented yet. Possibly the people over a PL have worked a little more on this, but I don't venture over there much.

I have not seen him selling any Optics that Clip the beam....His corrective optics will improve mRad and made it a bit more square, but its still not a dot.

His don't clip the beam. Dragon lasers clips their 445nm beam to square it up some.
