5.0 Preparing the microscope for use
Take the stereo microscope out of its packing and put it on a firm stable table. Connect the power
cable to the mains supply and switch on the microscope. Place the eyeshades onto the eyepieces.
Sit comfortably down behind the microscope and take a relaxed position while viewing through the
eyepieces (A). The third (photo) tube of the trinoculair versions is packed in the lid of the
styrofoam packing. Take it out and place it onto the microscope.
6.0 Working with the stereo microscope
The interpupillary distance
In order to obtain a
smooth “compound” image, one should go through the below steps.
The correct interpupillary distance is reached when one round image is seen in the field of view
(see image below). 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. When more 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 eye point
The eye point is the distance from the eyepiece to the user’s pupil. To obtain the correct eye point,
move the eyes towards the eyepieces until a sharp image is reached at a full field of view.
