Getting back into holography. Most set ups require 1 or 2 diverging lenses. Are there pros and cons to AR coatings? Also, from past experience, longer FL lenses take quite a bit of space to illuminate object. Is there any reason not to use very short FL concave lenses ( -6mm or -9mm). First set-ups will be split beam reflection, green plates, DPSS green laser(125mW), isolation table is 3'x5'.
