Base
Parts of a microscope: Eyepiece
-Magnifies the object 10x
-Can be 1 or 2 eyepieces present
Parts of a microscope: Nosepiece
Objective lenses (4x, 10x, 40x)
-Holds the lenses
Parts of a microscope: Stage elements
Stage Clips—holds the slide in place
Diaphragm—controls the amount of light
Parts of a microscope: Power, light, and focus
Coarse Adjustment-used to focus, moves the slide a lot
Fine Adjustment—used to focus, moves the slide a little
Light—shines through the specimen so it is visible
Power switch—turns the light on
Magnification and resolution
Magnification is the enlargement of a specimen.
To determine magnification you take: power of the eyepiece X the power of the objective
Example: A 10X eyepiece and a 4X objective magnifies
the specimen 40X.
How to see a slide
Put on low power
Put slide on stage/center
