A phase-difference microscope (or phase-contrast microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-difference microscope, living cells can be studied as they go through the cell division cycle.
HOW IT WORKS
As light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes.
A phase-difference microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible - and it is still alive!
This also works on reflected light microscopes.

What is an example of a simple microscope?
A light microscope is an optical microscope. That differentiates it from an electron microscope, a quantum mechanical tunneling microscope and others.

What is different types of microscope?
There are several type of microscopes, mainly, the one that we use in lab is a simple light microscope or a compound microscope. Then we have the phase contrast microscope, fluorescent microscope, electron microscope (transmission electron microscope [TEM] and scanning electron microscope [SEM]), confocal microscope and even dissection microscope the one which we use during dissections.
