Sorry, I do not know the proper terms for this subject, but...
Say I have a beam that is 6mm x 6mm and is reflected off of an engraved mirror. that beam needs to be concentrated in to a 200µm beam, while keeping the image quality.
if possible, please provide the lens dimensions
and to fugu, it is 100% photography related. just because you have ignorance in the subject doesnt mean you should be allowed to ban hammer every thing you fucking see. have some respect, im asking a question and really need help.
