PARTS OF A MICROSCOPE WHAT ARE THE PARTS OF A MICROSCOPE?

CAN YOU GUESS THE PARTS OF THE MICROSCOPE?

HOW DI D YOU DO?

OCULAR LENS (EYE PIECE) The part of the microscope you look through to see an image.

REVOLVING NOSEPIECE This part of the microscope holds the objective lenses and is able to rotate to change magnifications.

ARM This part on the side of the microscope is used to support it when it is carried.

OBJECTIVES LENS Objective lenses are used to magnify what you are looking at. They range from low to high power and are found on the nosepiece.

THERE ARE 3 OBJECTIVES: High power: 40 x Medium power: 10 x Low power: 4 x

What’s my power? CALCULATING “POWER” OR MAGNIFICATION Take the ocular lens 10 x To calculate the power of magnification, multiply the power of the ocular lens by the power of the objective. = 400 x And multiply it by the objective lens 10 40

STAGE The part of the microscope that supports the slide that is being viewed.

STAGE CLIPS These are used to hold a slide in place on the stage.

SPECIMENS Specimens are placed on slides and then placed on the stage. They are secured there by the stage clips. This keeps the slide from moving while you view it.

DIAPHRAGM This part helps you adjust the amount of light that reaches the specimen.

COURSE ADJUSTMENT KNOB This part moves the stage up and down to help you get the specimen into view and “find” the object.

FINE ADJUSTMENT KNOB This part moves the stage slightly to help you sharpen or “fine tune” what you are looking at.

LIGHT SOURCE Projects light upwards through the diaphragm to allow you to see the specimen.

BASE The bottom part of the microscope.
