An overview of purposes:
Matted lens (Fig. 2, 16) to be used for
• views with the PC eyepiece (Fig. 2, 4)
• viewing of extremely small items with
eyepiece (Fig. 2, 1+2) and Barlow lens
(Fig. 2, 3)
Condenser lens (Fig. 6, 17) to be used for
• viewing of standard items with eyepieces
(Fig. 2, 1+2) and Barlow lens (Fig. 2, 3)
5. Attach mechanical desk
A mechanical desk 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 mechanical desk (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.
6. Microscope setup
The microscope's eyepiece
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) to its lowest
position before changing the
objective in order to prevent
damage.
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).
7. 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.
(Fig 1,
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.
Tip:
i
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
the 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).
Tip:
i
Depending on the preparation
higher magnifications
not always lead to better
pictures.
