I'd only be interested if it was a simple solution for the 638nm beams. By simple I mean something that won't take 5 hours and steady hands to align and that won't need a custom machined holder (of course a holder will be needed, but IMHO it should be included).
Well.....these are some steep requirements ! The Mitsui P73
can be corrected, both in a hand held, see

and of course in a lab style.
I have done both, but the optical demands are the same;
1) Optimal positioning (centering) of the LD to the Collimation lens.
2) Mounting the cylindrical lenses with the most critical dimension being between the two lenses.
The complete correction of the P73 (638nm beams) is accomplished only when these two issues are addressed !
How one would accomplish these demands in a handheld format, other than the Dragon's Head design, I have no idea ! ...although there must be other ways ??
SOoooo....what is the end goal here ?? I assume we are addressing a hand held unit only. Really, the simplest and least expensive way I can imagine is the Dragon Head design. Perhaps, I am lacking imagination !! ?? Dunno
I suppose a single unit could be designed which would accomplish both demands 1 and 2 listed above !
But, what would this design fit into ? What would be the host ? It sure would be a custom design ! Simple ?? NO !! If the design is very good, alignment could and should be relatively easy. Not cheap, but not too expensive !
I suppose cost is relative !
And, I would speculate that the demand for such a unit would be limited. Thought's anyone ??????
