2. Definition of Microscope:
 The word microscope is derived from the Latin word “micro” means “small”
and the Greek word “skope” means “to look at”.
 A microscope is an instrument used to see objects that are too small to be
seen by the naked eye.
 It can magnify objects in a range from x100 to x400,000.

3. Parts of the Microscope:
Eyepiece
Neck
Stage
Adjustment
Light Source
Diaphragm
Stage Clips
Objective
Lens
Tube
Base

All
Nosepiece

4. Classification of Microscope:
 There are two main types of microscope on the basis of
magnification principles.
1. Light microscope.
2. Electron microscope.
 Light microscope also classified into five categories.
1. Bright field microscope.
2. Dark field microscope.
3. Fluorescence microscope.
4. Differential interference contrast.
5. Phase-contrast microscope.

5. Classification of Microscope:
 Electron microscope also divided into two types:
1. Scanning electron microscope ( SEM).
2. Transmission electron microscope (TEM).
 There are also some types of microscope.
1. Confocal microscope.
2. Scanned-probe microscope.

7. Ocular lens
• magnifies; where
you look through
to see the image
of your specimen.
• They are usually 10X or 15X
power. Our microscopes have
an ocular lens power of 10x.

8. arm • supports the tube and
connects it to the base

9. stage
• the flat platform
where you place
your slides

10. base
• the bottom of
the microscope,
used for support

11. body tube
• connects the
eyepiece to
the objective
lenses

12. objective lens
• Usually we will find 3
or 4 objective lenses on
a microscope.
• They always consist of
4X, 10X, 40X and
100X powers.

13. diaphragm
• controls the amount
of light going through
the specimen.

14. light
• makes the specimen
easier to see
