lighting (dimmer) optimal illumination of the
object to be viewed is guaranteed.
3. Colour filter disc
The colour filter under the microscope table
(Fig. 1, 19) aids in viewing very bright and
transparent objects. Just select the right colour
for the specimen in question. The components
of colourless/transparent objects (e.g. starch
particles, single-cell -specimens) can thus be
better recognised.
4. Attach stage
A stage is included along with your microscope
(located in the case, under the CD). To install this
on the microscope, proceed as follows:
1.
Place the stage (Fig. 4, 28) on the microscope
stage (Fig. 4, 8) in such a way that the
attachment screws (Fig. 4, D) are positioned
over the middle threaded hole (Fig. 4, E).
2. Tighten the attachment screws securely.
5. Microscope setup
The microscope’s eyepiece (Fig 1, 6) will now be
prepared for the first observation.
First, loosen the screw (Fig. 1, X27) and rotate the
eyepiece into a convenient position.
Begin every observation with the lowest magnification.
Place the microscope’s table (Fig. 1, 8) with the focus
knob (Fig 1, 9) into the lowest position and rotate the
objective revolver (Fig. 1, 7) until it locks on the lowest
magnification (4x).
NOTE:
First, drive the Microscope’s
table (Fig. 1, 8) in its lowest
position before changing the
objective in order to prevent
damages.
Insert the 5x eyepiece (Fig. 3, 1) in the Barlow
lens (Fig. 3, 3).
Take care, that the Barlow lens is inserted
completely in the monocular head (Fig. 3, 5).
6. Observation
After you have set up the microscope with
the corresponding illumination, the following
principles are important:
Begin each observation with a simple
observation at lowest magnification, so that
the centre and position of the object to be
viewed is in focus.
The higher the magnification the more light is
required for good picture quality.
Place a permanent slide culture (Fig. 5, 15)
directly under the microscope lens on the plate
(Fig. 5, 8) and clamp it on the cross-table (Fig.
5, 28). To do so push the lever (Fig. 5, C) aside.
The specimen to be examined must be directly
over the lighting. If not turn the two knurled
screws (Fig. 5, A+B) on the mechanical plate.
i
TIP:
On the mechanical plate (Fig
5, 28) there are two knurled
screws (Figs 5, A+B). They are
used to precisely position the
specimen laterally (Fig 5, A)
and vertically (Fig 5, B).
Look through the eyepiece (Fig. 1, 1/2) and turn
carefully the focusing wheel (Fig. 1, 9)) until
you can see a sharp picture.
Now you can get a higher magnification, while
you pull out slowly the Barlow lens (Fig. 6,
3) of the monoculare barrel (Fig. 6, 5). With
nearly entirely pulled out Barlow lens the
magnification is raised to 2x.
For still higher magnification you can put the
16x eyepiece (Fig. 2, 2) into the objective
revolver (Fig. 1, 7) and set on higher position
(10x / 40x).
i
TIP:
Depending on the preparation
higher magnifications do not
always lead to better pictures.
With changing magnification (eyepiece or
objective lens changes, pulling out of the
Barlow lens) the sharpness of the image must
