Answer:
Eyepiece Lens: the lens at the top that you look through, usually 10x or 15x power.
Tube: Connects the eyepiece to the objective lenses.
Arm: Supports the tube and connects it to the base.
Base: The bottom of the microscope, used for support.
Illuminator: A steady light source (110 volts) used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.
Stage with Stage Clips: The flat platform where you place your slides. Stage clips hold the slides in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs. One moves it left and right, the other moves it up and down.
Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope.
Microscope Rack StopRack Stop: This is an adjustment that determines how close the objective lens can get to the slide. It is set at the factory and keeps students from cranking the high power objective lens down into the slide and breaking things.
Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen.
Diaphragm or Iris: Many microscopes have a rotating disk under the stage.
