Getting Acquainted with Your Microscope

Learning About Your Microscope

1.

Eyepiece

– The eyepiece is where you look into the microscope. It is a

small magnifying lens that collects the image projected up by the three
objective lenses. Your microscope comes with two different eyepieces.
The 10X eyepiece makes an image look 10 times larger. The 20X
eyepiece makes an image look 20 times larger.

2.

Body Tube

– This is the main tube of the microscope. The image from the

sample travels up this tube to the eyepiece.

3.

Focusing Knob

– Turn these knobs very slowly to bring the image of

your sample into focus so you can see it clearly.

4.

Rotating Turret

– The turret holds the three objective lenses. Turn the

turret so that each lens clicks into position.

5.

Objective Lenses

– The objective lenses are the lenses closest to the

objects you are examining. Your microscope has three objective lenses,
each with a different magnifying power. The shortest lens has the lowest
magnifying power (5X). The longest lens has the highest magnifying
power (30X). The third lens has a magnifying power between the two
(15X). The objective lenses work with the eyepieces to give your
microscope a range of magnifications. With the 10X eyepiece in place,
your microscope makes samples look 50 times (50X), 150 times (150X),
and 300 times (300X) larger than they appear to your eyes. With the 20X
eyepiece in place, your microscope makes samples look 100 times
(100X), 300 times (300X), and 600 times (600X) larger than you can see
them with your own eyes.

6.

Arm

– This curved piece is the “backbone” of the microscope and holds

everything together. You can tilt the arm backward to get a more
comfortable viewing position.

7.

Stage

– The stage is the flat platform where your slides are held

for studying.

8.

Clips

– The two clips on the stage hold your slide in position so that it

doesn’t move around while you are looking at it.

9.

Mirror

– The mirror aims light from a bright source, like a sunlit window or

a table lamp, up through the slide you are studying so you can see the
specimen more clearly.

10.

Illuminator Lamp

– When there is not enough light available for the

mirror to do its job, turn the mirror over and the bright electric LED
illuminator will light your sample.

11.

Base

- The bottom of the base has a rubber cover to help prevent your

microscope from slipping on a smooth tabletop.
