Mirror - It is used to reflect light through the object and lenses of the eye.
The light is necessary when you are using a microscope because if you don't have the light turned on, then the object or specimen you would like to examine won't be showing up. The light makes you have the capabiltiy to see what your object looks like under the microscope, and if your light isn't being used, then you will not see your object, probably only darkness!!!

Lens
A light source on a microscope helps make the object that you're looking at easier to see. It brightens up the view so the object can be seen more clearly and can be more "in focus".
So that you are looking at the details of the object and not the light.
Fine focus is typically in reference to studying an object under a microscope. Fine focus means that the person operating the microscope focuses on one part of a specimen at a time.

Coarse focus on a microscope is used only when you are using the lowest objective lens. You use it to get the object magnified mostly. The fine focus is then used to adjust the resolution to the viewer's eyesight.
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away

The function of the coarse adjustment knob on a microscope is to lower or raise the stage of the microscope. This mechanism is used to focus the specimen.
