Looking for a (semi-cylindrical?) lens that'll take a +/- 2mm beam, and give me a nice flat divergence such that it projects a line, rather than a spot. Preferably glass - I could be passing up to 8W of 445nm through it, so I want to have the thing have a fairly high optical damage threshold.
Thanks for any direction. Searching yields very little useful info. Chinese companies that can get me a lens in 20+ weeks, and 10k hits for "laser line levels", so I must be using the least effective keyword possible
EDIT: I think I'm looking for a "Powell Lens"...
