The compound light microscope, combines the power of lenses and light to enlarge the subject being viewed.
The Stereo microscope, also called a dissecting microscope, has two optical paths at slightly different angles allowing the image to be viewed three-dimensionally under the lenses.
It is known as the sedimentation.. this process spreads widely (horizontally) keeping the youngest on the top and the oldest at the bottom.. hope this helps:)
