Handleiding

EXPERIMENT 2

The first specimen:

“natural fibers”

YOU WILL NEED

› Natural fiber prepared slide

› 2 1.5-volt batteries (AA/LR6/Penlight)

HERE’S HOW

1. Before viewing your first specimen, you will

first have to insert the batteries for the lamp.

You will find the battery compartment on the

underside of the base.

2. Turn the microscope’s illumination unit so

that the mirror is pointing downward. The

light will switch on automatically. The bulb’s

light will shine through an opening in the

stage, with the diaphragm letting more or

less light through depending on its size.

Always start by selecting the largest

diaphragm setting.

3. Take the prepared slide and clamp it under

the clips on the stage. The specimen should be

positioned as precisely as possible over the

center of the stage opening so it is well

illuminated by the bulb.

1: base, 2: battery

compartment cover, 3:

arm, 4: illumination unit

(mirror and lamp), 5:

stage with clamps and

adjustment wheel, 6:

nosepiece with three

objective lenses, 7: fine

adjustment, 8: eyepiece

with turning function

NOTE!

At the strongest magnification (500x – 750x),

the objective is so long that you have to be careful not

to let it hit the slide!

Pay attention to the correct orientation of + and – !
