Thats really, up to you. Try asking your manufacturer for the divergence when focused to infinity. We may get some interesting results. Gotta sleep, bb.
I was thinking about this, over the last few days, and wondered ...
besides trying to change the shape of the beam, ... with a lens,
are you also trying to change the physical angle or divergence it emitts, back to being on true center?
'cause for that, I suggest making some michanical micro-adjusting "gizmo",
to allow you to actually move the module, slightly, left-right-up-down, and rotate, within the host.
wouldn't this take care of divergence adjustments? ... sort-of, like a gun site adjustment.
Then you can concentrate on shaping the beam with the lens system you choose.
BTW-they did say the measurement was taken from the bare window of the diode.
I'm asking them again, if the wide difference in minimum and maximum values are,
production run changes, or higher current inputs changing divergence values.
I think, however, being it's a medical device laser, it's meant to use within 1 meter.
Think about it... ... you gunna shoot da lazor to da patient 'cross da room?
sorry, just being silly again... but really now .. you're wanting to make the diode go to infinity,
or shape a certain way, any diode will need some amount of tweaking,
plus, if you actually expect to have a production run diode be perfect,
it's going to cost plenty, at least, at first, when it's newly released, and
not requested in million quantity by some consumer product manufacturer, later on.
