The first intermediate lens magnifies the initial image
that is formed by the objective lens:
The lens can be focused on:
- Initial image formed by the objective lens, or
- Diffraction
pattern formed in the back focal plane of the objective
lens.
This determines whether the viewing screen of the microscope
shows a diffraction pattern or an image.
Will
the diffraction pattern be magnified as much by the intermediate
lens as the image is? Explain your answer.
