Principles of a phase microscope
There is a hook-like slit between the condenser lens and the lighting, and a phase plate is located
inside the object lens.
When light is emitted from the lighting of the phase microscope, the light which passes through
the hook-like slit doesn’t change the direction of the light which passes
through the part of the object (sample) with the same refractive index.
When the light passes through the phase plate, it delays the phase by π/2 or 3π/2.
Meanwhile, the light which passes through the part with a different refractive index changes
its direction due to a diffraction phenomenon. Thus, the light passes through a part other
than the hook-like slit without delaying the phase.
These two lights meet at the location of the object’s image, and due to the interference,
there is a phase-difference which changes into a difference of brightness proportional
to the phase-difference. Such difference is enlarged and observed by the ocular.
