Answer:
Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens.
Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.
Body tube (Head): The body tube connects the eyepiece to the objective lenses.
Arm: The arm connects the body tube to the base of the microscope.
Coarse adjustment: Brings the specimen into general focus.
Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses.
Objective lenses:One of the most important parts of a compound microscope, as they are the lenses closest to the specimen.
Specimen or slide: The specimen is the object being examined. Most specimens are mounted on slides, flat rectangles of thin glass.
Stage: The flat platform where the slide is placed.
Stage clips: Metal clips that hold the slide in place.
Stage height adjustment (Stage Control): These knobs move the stage left and right or up and down.
Aperture: The hole in the middle of the stage that allows light from the illuminator to reach the specimen.
On/off switch: This switch on the base of the microscope turns the illuminator off and on.
Illumination: The light source for a microscope. Older microscopes used mirrors to reflect light from an external source up through the bottom of the stage; however, most microscopes now use a low-voltage bulb.
Iris diaphragm: Adjusts the amount of light that reaches the specimen.
Condenser: Gathers and focuses light from the illuminator onto the specimen being viewed.
Base: The base supports the microscope and it’s where illuminator is located.
