Hello,
I've come across an problem that requires the lens to be at least about 350 mm away from the object.
Object to be examined is 80 mm tall and imaging plane is either 11 mm or 25 mm tall. I've tried to calculate required focal length, but have not succeeded. Distance from lens to imaging plane is not known.
See attached picture for clarification.
