Epi-illumination: the most common type used in IC RE.  A typical setup has a side lamp that hits a half silvered mirror between the objective and the eyepiece.  Light hits the mirror to reflect towards the sample and bounces back.  Half of that light reaches the eyepieces and that is the image you observe.  This can produce thin film interference patterns to distinguish even same color specimens.

Biological: the most common type of microscope most people encounter.  A typical setup has a lamp in the base that shines light through a condenser that focuses light through a sample and into the objective and then into the eyepiece.  Since most IC samples are opaque this type of microscope is not suitable for IC work.  However, as a move of desperation, you can use one by shining light from the side.  This is how I did my early IC work.  Things are much better if you can get a hold of a fiber illuminator, but chances are if you can afford a fiber illuminator you can afford a cheap epi-illumination microscope.

Polarized light can bring out a lot of interesting effects and help reduce glare. However, if you don't use strain free objectives you will get effects like this:
