A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto the microscope slide - the diaphragm controls how much light enters the microscope. The base is heavy to keep the microscope from falling over. The arm of the microscope holds the eyepiece lens above the stage. Both focus knobs are used to make sure
