MICROSCOPE

A microscope allows you to observe objects

which are too small to be seen with the naked eye.

To maximize your laboratory experience in the

study of cells and tissues you must master the use of

a microscope.

Here are a few rules which will protect the

microscopes from damage:

1-Always Use Two Hands to Carry the Microscope. One Hand Should Be on the Base and One Hand on the Arm.

 

2-Never Touch the Lenses of the Microscope with Anything.

 

3-Turn Off the Light and Return the Lenses to the Lowest Power Position before Returning the Microscope to the Storage Area.

The Total Magnification of a Microscope

The total magnification of a microscope is

calculated by multiplying the magnification of

the ocular (10X) by the magnifying power of

the objective. Thus the total magnification using

the low power objective is 100 times (100X). This

is calculated by multiplying 10 (ocular) times 10

(low power objective).

Exercise 2.1

Write the name of each part of the microscope in the

blanks in Figure 2.1 or Figure 2.2. (Label only the

drawing which most closely matches your microscope).
