I have two measurement cases in my setup. An divergating laser beam (not an gaussian) is measured at two locations from lens , at nearby i.e. 400 mm, and far away, > 2000 mm away. My lens is an plano-convex lens.
Which side should face the laser in these two cases?
I know that the plano-concave lenses, with the curved side to the laser source removes spherical aberrations,. is this also true for a divergaing beams?
My goal is to image the source onto a camera.
