Preparing the stereomicroscope for use
Carefully remove the items from its packaging and place them on a flat, firm
surface. Please do not expose the stereomicroscope to direct sun light, high
temperatures, damp, dust or acute shake. Make sure the table or surface is flat
and horizontal. When moving the stereomicroscope, use one hand to hold
the pillar or column and the other hand to hold the base
Caution!
Holding the stereomicroscope by its focusing knobs
will damage it
Caution!
If the bacterial solution or water splatters over the stage
plate, objective or head, pull out the power cord immediately and
dry the microscope
Assembling steps
Mounting the head
Remove the microscope head from its packaging and mount it on the microscope head holder. To do so, loose the
head fixation screw (C) so that the head can be inserted all the way into the head holder. Once the head is in place,
tighten the head fixation screw again. The photo tube of the trinocular versions is packed in the lid of the foam
packing. Take it out and screw it into the photo tube port (H)
Placing the eyepieces
Unpack the two eyepieces (A) and remove their dust covers. Then
remove the dust covers of the eyepiece tubes and insert the two
eyepieces into the tubes (the eyepieces should be pushed all the
way down, touching the tubes). The eyepieces can be secured with
a hexagon type screw. The exact location of the hexagon screw may
differ. Each eyepiece has its rubber eyeshade. This prevents damage to
the lens and prevents stray light. The eyeshade can simply be slipped
over the eyepiece
Connecting the microscope
Connect the power cable to the mains supply and switch on the
microscope using the On/Off switch (O). Do not bend or twist the
power cord as damage may occur. Use the power cord supplied with
the unit. If the cord requires replacement, ensure that it is suitably
rated. If in doubt consult your local dealer or qualified electrician.
Working with the stereomicroscope
The interpupillary distance
In order to obtain a smooth “compound” image, follow these steps.
The correct interpupillary distance is reached when one round image is seen in the field of view (see image at right).
This distance can be set by either pulling the tubes towards each other or pulling them from each other. This distance
is different for each observer and thus should be set individually. If several users are working with the microscope it is
recommended to remember your interpupillary distance for a quick
set up during new microscopy sessions
The correct eyepoint
The eyepoint is the distance from the eyepiece to the user’s
pupil. To obtain the correct eyepoint, move the eyes towards the
eyepieces until a sharp image is reached at a full field of view
