As your device has continuously controllable
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).
