QuestionAnswer
Microscope an instrument that produces an enlarged image of an object
Lens an optical device that refracts (Bends) light to form images
Simple microscope a microscope with one lens
Compound light microscope named because they use two or more lenses to magnify objects. Highest possible magnification is 1,000X We use a microscope of 400 x
Electron Microscope Do not use lenses to direct light; they use electrons (negatively charged electrical particles) to magnify objects up to 2,000,000X!!! allow scientists to view things too small to be seen with a light microscope. Used to observe atoms and molecules
Eyepiece Lens   the lens at the top that you look through. 
Body Tube  Connects the eyepiece to the objective lenses.
Objective Lenses Usually you will find 3 objective lenses on a microscope.  They almost always consist of 4X, 10X, 40X - magnify objects/specimens 
Nosepiece This is the part that holds the objective lenses and can be rotated to change power.
Base The bottom of the microscope, used for support.
Arm Supports the tube and connects it to the base
Light source found near the base of the microscope; makes the specimen easier to see.
Stage The flat platform where you place your slides.
Stage clips found on the stage; hold the slides in place.
Diaphragm rotating disk under the stage; different sized holes vary the intensity and size of light that is projected upward into the slide.
Coarse adjustment knob large, round knob on the side of the microscope used for focusing the specimen; it moves the stage up and down.
Fine adjustment knob small, round knob on the side of the microscope used to fine-tune the focus of your specimen after using the coarse adjustment knob.
Magnification is the process of enlarging something only in appearance, not in physical size
Field of View The area of the slide that you see when you look through a microscope; it is the circle of light.
