Adjustment knobs are used to focus light in a light microscope.
A simple microscope has two lenses. One the eye looks through and the objective lens nearest the object being observed. Changing the objective lens changes the magnification of the microscope, and can also change the amount of light on the object. The objective lens draws the light rays together to make a sharp image.
The condenser and its diaphragm.
The diaphragm regulates the amount of light that reaches the objective lens. It is also called the iris.
So light can pass through the slide to the objective.
The objective lenses on a microscope collects light and brings the specimens into focus.
