3. General/Location
Before you set up the microscope, you must choose a suitable location.
First you must make sure that your microscope is on a stable and solid surface
4. Electric illumination
It works, by plugging the connection cable into the microscope socket (19) and
plugging the AC adapter into the mains socket.
The switch at the rear of the microscope must be switched on.
HINT for the rechargeable battery:
Your microscope is fitted with one built-in rechargeable battery. A fully
charged battery allows ca. 48 hours of observation. Before using the
microscope for the first time the rechargeable battery should be charged for
16 hours. Please charge it by connecting the microscope socket (19) with the
included AC adapter and plugging the AC adapter into mains socket.
5. Observation
You begin each observation with the lowest magnification (eyepiece 10x and
objective 4x). So, the object to be viewed can easily be cantered and properly
focussed. The higher the magnification the more light is required for good
image quality.
For applications with the 100x lens, it is recommended that examinations are
done only with oil immersion.
Begin with a simple observation. Turn the objective revolver (4) onto the
smallest magnification and insert the 10x eyepiece. Now place a preparation
directly under the objective on the microscope table. Move the preparation on
the table with the two adjusting screws (14 and 15).
Now look through the eyepiece (1) and turn the coarse adjustment (12)
carefully until the image becomes visible. The optimal sharpness is achieved
by the fine adjustment (13).
Make sure that you never overwind the fine adjustment.
6. Condenser
Use the condenser height adjustment knob (10) to properly concentrate the light for your object.
7. Iris diaphragm
An iris diaphragm (8) is available if you want better image quality. This makes it possible to change perspective depth. The smaller the aperture the greater the perspective depth. However, image brightness is also reduced. You can compensate for this by adjusting the brightness using the dimmer (16)
8. Filter holder
Push the filter holder (9) forwards and then insert the blue filter if you wish to use it. The filter holder can then be pushed back again. This filter is used to show natural colours.
9. Oil immersion (only for 100x objective)
The immersion oil is only necessary for the 100x objective. Apply one drop of immersion oil onto the upper condenser lens. With the slide clamp (6), fix your prepared slide on the mechanical desk. Using the condenser height adjustment knob (10), move up the condenser (7) carefully, until the slide touches the immersion oil. Focus the preparation with the 100x objective and the fine focuser as good as possible. Now turn the objective revolver a little bit to the side and apply one drop of immersion oil onto the preparation’s covering glass. Turn back the objective revolver. The objective must dip into the oil! Now the preparation can be focused. Don’t forget to clean objective and preparation with alcohol after observing.
NOTES on cleaning
- Avoid disassembling the microscope! Because it is a precise optical instrument, do not disassemble the microscope casually. That may cause serious damage to its performance. Do not disassemble the objectives.
- Avoid contamination! You should make sure that dust or moisture do not get in contact with your microscope. Avoid touching optical surfaces with your fingers! If dust or dirt nevertheless have gotten onto your microscope, or the accessories, remove it as described below.
- Cleaning non-optical parts: Disconnect the plug from mains socket before cleaning non-optical parts of the microscope (e. g. the body or the stage). First, remove dust or dirt from your microscope, or accessories, using a soft brush. Then clean the dirty area with a soft, lint-free cloth; the cloth may be moistened with a mild detergent solution. Be sure that the microscope is dry before using. For cleaning the painted parts or plastic components, do NOT use organic solvents such as alcohol, ether, acetone, xylene or other thinner etc.!
- Cleaning optical parts: In order to enhance the optical quality, the lenses of eyepieces or objectives are coated. They should not be wiped because dry dirt or dust may scratch the coating. It is best to remove the parts to be cleaned from the body prior to cleaning. Always blow loose dust away first. Use lens tissue of good quality or soft fabric moistened with a small amount of pure alcohol (available in the pharmacy); wipe the lens surface clean.
- Cleaning the oil immersion lens: After working with oil immersion, the immersion oil should be removed from the lens of the 100x objective at the end of each workday. In order to do this, use a lens tissue moistened with a small amount of pure alcohol (available in the pharmacy). Don’t forget to clean the preparation, too.
- Storing the microscope: After usage, cover the microscope with the dust cap (made of plastic) and keep it at a dry place, away from mold. If it is not used for a prolonged time, store the microscope and accessories in their respective containers.
Remember: A well maintained microscope will keep its optical quality for years and thus maintain its value.
Technical data
Monocular head
Mechanical desk (with vernier alignment)
Eyepiece: DIN WF 10x
Objectives: DIN 4x / 10x / 40x / 60x or 100x (oil)
Magnification: 40x – 600x or 1000x
Illumination: rechargeable battery LED
Technical alterations and errors excepted.
Aperture: The numerical aperture (the unit of measurement for the
resolution factor of the objectives) is engraved beside the magnification-sign
on the objectives.
The magnification for microscopes is calculated by formula: Eyepiece magnification x objective magnification factor = total magnification
Example: 10x eyepiece x 100x lens = 1000x total magnification
Disposal
Dispose of the packaging materials properly, according to their type (paper,
cardboard, etc). Contact your local waste disposal service or environmental
