microscope - An instrument for viewing objects that are too small to be seen by the
naked or unaided eye (micro: Greek for small, Scope: Greek for looking at)
electron microscope - A type of microscope that uses electrons to illuminate a specimen
and create an enlarged image. Electron microscopes have much greater magnification-
sometimes as high as 2 million times.
eyepiece - The part of the microscope used for viewing a specimen. Also called the
occular lens. On our microscopes this lens magnifies 10X.
nosepiece - Holds the low-power, medium- power, and high-power objective lenses;
allows the lenses to rotate for viewing.
objective lenses - Lenses located on the nosepiece; on our microscopes they magnify 4X,
10X, and 40X.
diaphragm - Controls the amount of light passing through the opening in the stage into
the objective lens.
base - Supports the microscope. Microscopes should always be carried with one hand on
the arm and one hand on the base
arm - Supports the body tube and should always be facing you
stage - Platform on which the specimen rests
convex lens - A curved lens in which the center is thicker than the edges
slide - Piece of glass which holds the specimen under the objective lens
