Apparently some microscopes (?polarizing or phase contrast) can be used to study fine scale roughness of lens surfaces (eg eyepiece lenses or objective lenses). I would be interested in obtaining such a microscope if the cost was not prohibitive. All advice on this topic is greatly appreciated,

Thanks,

Alan
