Different between ocular and compound miscroscope

One system of lens - ocular microscope

Two systems of lens - compound microscope

Some of the parts of a compound microscope are the eyepiece lens. There are two knobs on under the other to one side of the microscope which are used for Coarse focus and Fine focus. There is an illuminator at the bottom of the microscopic stand, which sheds a powerful light on the subject under the lens. Other parts include objective lenses, stage with stage clips (where the subject is placed) and r evolving nosepiece. The tube connects the eyepiece lens to the turret.
