Microscope Information
Microscopes are used
to magnify specimens
that are too small to
see with the unaided
eye.
1. Arm
2. Stage Clips
5. Eyepiece
6. Body Tube
7. Nosepiece
8. High Power Objective
9. Low Power Objective
10. Stage
3. Coarse Adjustment Knob
4. Fine Adjustment Knob
11. Diaphragm
12. Light Source
13. Base
Functions:
1. Light Source – (D) provides light for viewing specimen
2. Stage – (B) Supports the slide
3. Stage Clips – (I) Hold slide in place
4. Coarse Adjustment Knob – (F) brings image into initial focus
5. Fine Adjustment Knob – (A) sharpens focus
6. Diaphragm – (C) Controls the amount of light passing through the
stage
7. High Power Objective Lens – (H) 40X or 43X magnification
8. Low Power Objective Lens – (G) 10X magnification
9. Revolving Nosepiece – (E) Holds the objectives and can be rotated
to change magnification.
Microscope Information
Carry a microscope
with one hand
under the base and
one hand on the
arm.

Microscope Information
Clean microscope
lenses with lens
paper only.
LENSES
Total Magnification:
Eyepiece (10X) x Low Power Objective (10X) = 100 X
Eyepiece (10X) x High Power Objective (43X) = 430X
Field of View:
Area within the circle of light
How to Focus A Microscope:
1. Lower Stage using C.A.K.
2. “Click” low power obj. in place
3. Put slide on stage; secure w/ stage clips
4. Raise stage using C.A.K. until it can no longer move
5. Look through eyepiece & slowly roll the C.A.K. down until
specimen appears.
6. Use F.A.K. to sharpen image
To View Under High Power:
1. Use rev. nosepiece to switch to high power obj. lens
2. Adjust slide on stage until specimen is in field of view
3. ONLY use F.A.K. to focus image
