I want to image a diffuser (e.g. 1500 grit glass diffuser). Is it possible to do so using a microscope objective and normal (say aperture f/8) lenses?
When i say imaging a glass diffuser, it means imaging the whole phase function so I should not be able to see any speckles in the conjugate image plane even if illuminating the diffuser with a laser beam!
Could anyone provide me with few estimates of the numbers in terms of NA of corresponding objective and f/# of lenses to achieve this?
