Microscope Parts & Usage
Contains the magnifying lens you look through.
EYEPIECE
Which objective lens would you use for first focusing the object?
SCANNING
Scientist known for contributing to the third part of the ‘Cell Theory’
which states that all cells come from other cells.
VIRCHOW
Maintains the proper distance between the
eyepiece and the objective lenses.
BODY TUBE(BARREL)
Which adjustment knob should be used on scanning power?
COARSE ADJUSTMENT KNOB
Scientist who observed “animalcules”, also
known as bacteria and protozoan.
Van LEEUWENHOEK
Supports the body tube and stage; used to carry
the microscope.
ARM
Statements about cells that apply to all living things
developed with use of the microscope.
CELL THEORY
Which adjustment knob should be used while on
high power?
FINE ADJUSTMENT KNOB
Scientist who observed the first cells and came up with the word ‘cells’.
HOOKE
Located on the stage, holds the slide in place.
STAGE CLIPS(SLIDE CLIPS)
The name for a microscope with one
ocular lens (eyepiece).
MONOCULAR
Scientist who studied plant cells and helped
contribute to the ‘Cell Theory’.
SCHLEIDEN
Moves the stage up and down for focusing an
image; used first when focusing the specimen.
COARSE ADJUSTMENT KNOB
Term used to describe a microscope with two sets
of magnifying lenses.
COMPOUND
Moves the stage slightly to sharpen the focus of
the image; used only with the higher power objective lenses.
FINE ADJUSTMENT KNOB
Scientist who studied animal cells and helped
contribute to the ‘Cell Theory’.
SCHWANN
Provides electricity in order to operate the
microscope.
POWER SWITCH
A tool used to view small objects that cannot be
easily seen by the naked eye.
MICROSCOPE
Holds the objective lenses and allows them to be
rotated during use.
NOSEPIECE
This term is used to describe a microscope
that remains focused on high power once focused
on scanning power.
PARFOCAL
Magnifying lenses located closest to the specimen
being viewed.
OBJECTIVE LENSES
The white circle you see when you look through the eyepiece with the
light turned on.
FIELD OF VIEW(VIEWING CIRCLE)
Allows light to go through the stage, specimen, and the lenses to your eye.
STAGE OPENING(APERTURE)
What is the formula used to calculate total magnification?
OCULAR LENS x THE OBJECTIVE LENS IN USE(ex. 10x times 40x = 400x)
Supports the slide being viewed; should be all the
way up before first focusing the specimen.
STAGE
Scientist given credit for developing the first
microscope.
JANSSEN
Regulates the amount of light allowed through the
specimen and into the body tube.
DIAPHRAGM
Where should you look when changing from the
scanning power to a higher power?
TO THE SIDE OF THE STAGE
(NOT THROUGH THE EYEPIECE)
Provides light necessary to view the specimen.
LAMP(LIGHT SOURCE)
Supports the weight of the entire microscope; used to
carry the microscope.
BASE
Which objective lens provides the greatest
field of view?
SCANNING
