What is a Microscope?

The microscope is made of two lens systems: the eyepiece and the objective. We’re presenting these systems as one lens each so that it‘s easier to understand.
In reality, however, the eyepiece (1) and the objective in the turret (3) are made up of multiple lenses. The lower lens (objective) magnifies the prepared specimen (e.g. 11), which leads to a magnified image of the specimen.
The picture, which you can’t see, is magnified once more by the second lens (eyepiece, 1). Then, you can see the “microscope picture.”

Assembly and Location

Before you start, choose an ideal location for using your microscope. On the one hand, there must be enough light (normal observation).
On the other hand, it’s important that you can quickly make the room dark when you want to (projector observation).
Furthermore, I recommend that you place the microscope on a stable surface since you won’t be able to get any satisfactory results on a shaky surface.

Normal Observation

For normal observation, place the microscope in a bright location (near a window or desk lamp, for example).
Remove the microscope from the package and tilt the microscope arm (9) so that it’s in a comfortable viewing position for you.
The focus knob (2) is turned to the upper stop and the objective turret (3) is set to the lowest magnification.
Now, take a look through the eyepiece and adjust the mirror (5) so that you get a uniformly bright circle of light. Or, you can use the lamp. You’ll find further tips about the lamp in the next chapter. Now, place a prepared slide (e.g. 11) under the clips on the stage (4), directly under the objective. When you take a look through the eyepiece, you can see the magnified specimen. At this point, it might still be a slightly fuzzy picture. The sharpness is adjusted by slowly turning the focus knob (2). You can now select a higher magnification by turning the objective turret and selecting a different objective.
In doing so, note that the sharpness of the picture must be adjusted again for the higher magnification. Also, the higher the magnification, the more light you will need for good illumination of the picture.
TIP: Avoid positioning the mirror so that it is exposed to direct sunlight since it can cause a glare, which won’t allow you to get a clear picture.
The Colour filter wheel (22) below the microscope stage (4) will help you in viewing very bright or clear-sighted preparations. Turn the wheel (22) till the best contrast is achieved.

Electric Illumination

Before first use: Gently pull the battery insulation of the LED lamp to remove it.
To use the LED lamp (6a), you need two LR41 batteries (1.5 V), which are installed in the Mirror/LED lamp of the microscope (7). Remove the Mirror/LED lamp from the arc holder. \
Loosen the screw on the side with a small Phillips screwdriver and insert the batteries according to the displayed +/- information. Reattach the mirror cover and tighten the screw. Replace the Mirror/LED lamp in the holder.
You can turn on the light with the light on/off switch (6b). Take a look through the eyepiece and adjust the light so that you get optimal picture brightness. Now you can observe in the same way as described in point 1.3.
The bulbs for the electric light can be replaced. When you use another bulb, make sure to pay attention to the maximum wattage, which is displayed on the lamp body.
TIP: The higher the magnification used, the more light is required for a good illumination of the picture. Therefore, always start your experiments with one of the lower magnifications.

How do I make thin specimen slices?

Only do this with the supervision of your parents or another adult.
To get the best results, you will need some wax or paraffin.
It is best if you use a candle. Place the wax in a pot and heat it carefully over low heat. Now, dip the object in the liquid wax a few times.
Then, let the wax get hard. Using a knife/scalpel, cut the smallest slices from the object that is covered with wax. These slices are to be laid on a slide and covered with a cover slip.

How do I make my specimens?

Take the object that you want to observe and place it on a glass slide (13). Then, add a few drops of distilled water to the object using a pipette.
Now, place a cover slip (12) vertically at the edge of the drop of water, so that the water runs along the edge of the coverslip. Then, slowly lower the cover slip over the water drops.

Troubleshooting

Error	Solution
No recognisable image	• Turn on light

• Readjust focus

Make sure your microscope has a long service life.
Clean the lens (objective and eyepiece) only with the cloth supplied or some other soft lint-free cloth (microfibre). Do not press hard as this might scratch the lens.
Ask your parents to help if your microscope is very dirty. The cleaning cloth should be moistened with cleaning fluid and the lens wiped clean using little pressure.
Make sure your microscope is always protected against dust and dirt. After use leave it in a warm room to dry off. Then install the dust caps and keep them in the case provided.
