non-optical parts of the microscope (e. g. the frame or the
stage). Firstly, remove dust or dirt from your microscope, or
accessories, using a soft brush. Then clean the soiled 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.!
4. Cleaning optical parts
In order to enhance the optical quality, the lenses of eye-
pieces 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 frame 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 chemist's shop); wipe the
lens surface clean.
5. 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 moi-
stened with a small amount of pure alcohol (available in the
chemist's shop). Don't forget to clean the preparation, too.
6. Being not used
After usage, cover the microscope with the dust cap (made
of plastic) and place it where it is dry and mouldless. In
the case of non-use for a longer time, you should stow the
microscope and the accessories in their correct containers
again. We suggest the storage of all objectives and eyepi-
eces in a closed container with drying agent.
Remember:
A well maintained microscope will keep its optical quality
for years and thus maintain its value.

Monocular head
Mechanical desk (with vernier alignment)
Eyepiece: DIN WF 10x
Objectives: DIN 4x / 10x / 40x / 100x oil
Magnification: 40x -1000x
Illumination: Accu-LED
Accessories: Immersion oil
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 magnifi-
cation
