1) Eye Piece (ocular)
  • the lens that you look through

2) Body Tube
  • the tube that supports the eyepiece

3
3) Revolving Nosepiece-
the rotating device that holds and changes the
objectives (lenses).
Revolving
Aperature-
Opening in the stabe to allow light from mirror
or light to pass
4
4) Low Power Objective
  • magnification lens with the lowest power

5) High Power Objective
  • magnification lens with the highest power

6) Stage Clips
  • clips that keep the slide or specimen from moving
  • on the stage

5
7) Stage
holds the specimen

8) Diaphragm-
controls the amount of light entering through the
aperature to the objectivefrom the bottom

9) Pivot Point-
Pivot Point
part that allows you to tip the ocular toward you
Mirror
Base
10) Base-
supports the microscope
11) Mirror
reflects (bends) the light upward onto the slide
8
12) Fine Focus Adjustment
moves the body tube in small increments
13) Coarse Focus Adjustment-
moves the body tube in large increments
14) Arm
attaches the eyepiece and the body tube to the
base

Magnification
A how to guide...
10
Calculate Total Magnification
Total Magnification
ocular power x objective lens power using
Ocular power is generally 10X, meaning it has a
magnification or power of 10X
