Your Microscope

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, howev-er, the eyepiece (1) and the objective in the tur-ret (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, it‘s important there is 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.

Electric Illumination

NOTE! Before initial operation, the foil used for protecting the battery from discharging must be pulled out of the battery compartment.

Locate the mirror/light on the base of the micro-scope. Flip the mirror/light with the light facing up and press the button to power on the light. This microscope is equipped with an incandescent light that illuminates the specimen from below.

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.

Battery change

Remove the safety screw from the cover.
Remove the battery cover.
Slide out the coin battery holder.
Install the CR2032 coin battery with the positive (+) polarity facing down and the negative (-) polarity facing up on the holder.
Replace the battery cover.
Screw in the safety screw back to the cover
