(Using quality coated glass.)
Aspheric vs. Plano-Convex lens type:
What do each of these lenses do with an emitters light, in comparison to one another? They focus it to an image at distance I know, but what one will do a better job and why? Say each is same diameter, same focal length, or is that just not possible to have between two different lens types like these?
Thank you flashaholics!
Edit: ...For projecting the light of an LED this question applies to, of course.
