2. Starting Operations
2.1. Assembly
Please open carefully the packaging of the
microscope.
At first the microscope stand (10) has to be
taken out of the packaging and has to be put on
a plan subsoil. After that the incident light tube
(4) has to be set on the quick-change equipment
of the microscope stand. Clamp it with the
screw.
The binocular straight tube (2) and the angled
tube (3) has to be taken from the packaging.
Assemble the binocular straight tube into the
quick-change equipment of the angled tube and
clamp it with a screw.
Take this pre-assembled parts and set them to the
quick-change equipment of the incident light tube
and clamp it with the screw.
Now the objectives will be taken out of their
protective packaging and the objectives has to
be placed into the revolving nosepiece (5) in
this way, that if the revolver will be rotated
clockwise, the magnification will be increase.
The stage (gliding stage, stage carrier with
object guide or stage carrier with rotary table)
will be done into the stage holder (7) and will
be clamped. The adjustment of the objectives
will be done by the combined coaxial coarse
and fine drive adjustment (9).
At last the eyepieces GF – Pw 10x/20 (1) will
be assembled into the binocular straight tube.
The eyepiece can be used with or without
eyecups. The eyepiece is usable as eyepiece for
spectacles. To avoid dirt within the tube, the
eyepieces should be stay the whole time in the
tube.
The power connection of the incident light tube
can be found on the backside of the microscope
base (8). The intensity of the incident light
illumination can be set by the adjustment in front
of the microscope base.
Further it is possible to use different filter in the
filter holder of the incident light tube.
2.2. Adjusting the sharpness
The adjustment of the sharpness is only
necessary if the binocular straight tube is in use.
The microscope can be adjusted in that kind that
a sharp image is the result at all levels of
magnifications.
You can achieve this in the following way:
- The distance of the eyepieces has to be
adjusted by screwing up the eyepiece cone to
the individual interpupillary distance.
- The left dioptre ring has to be adjusted to -0- .
- Adjust a sharp picture with help of the drive
mechanism (you have to look with the right eye
through the right eyepiece).
- You have to adjust the sharpness on the left eye
by adjusting the dioptre ring.
2.3. Incident light illumination
The incident light illumination tube consists a
intermediate tube with a tube factor of 1x or
1,6x, an illuminating adapter and a 3W-LED
illumination.
The objects will be illuminated by a 3W-LED
incident light illumination (Koehler principle).
The aperture diaphragm and the field
diaphragm are integrated in the illuminating
adapter.
