The stereo microscope consists of two separate microscope tubes which are combined as a unit,
in order to focus them simultaneously on the object. Each tube has prisms, achromatic objectives
and a widefield eyepiece in order to obtain a large, flat field of view. Both eyes are looking at the
object under a different angle to reach a deep stereoscopic image.

The maintenance requirement is limited when using the microscope in a decent manner.

This manual describes the construction of the microscope, how to use the microscope and
maintenance of the microscope.

4.4 Focusing
With the focusing knobs (K) the object can be sharply focussed.

The microscopes are equipped with 2 achromatic zoom objectives. By using the zoom knobs ()
the magnification can be adjusted in a smooth, stepless way
4.61lumination
The stand is equipped with transmitted and incident LED ilumination of 3 Watt. The iluminators
can be used simultaneously. Intensity of the LED's can be controlled using controllers (E) and (L).

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 viewingthrough the
eyepieces A) Thethird (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.

Field of view before Field of view after

adjustment adjustment

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.

6.1 Setting the eyepiecesin orderto have asharp image overthecomplete zoomrange
Setting up your stereo microscope properly is essential to getting parfocal images during the entire zoom
range. It also prevents head aches, stressful eyes and fatique. Below you will find a set up guide that will help
get the best out of your microscope

Digital cameras can also be used in combination with a binocular. Simply remove the eyepiece
and placethe camera adapter ring inside the eyepiece tube. Then place the camera with mounted
C-mount adapter into the eyepiece tube. Focus the digital image with the coarse and fine controls
of the microscope. Also see instruction on next page.

Follow the manual that comes with the camera for camera operation.

7.2 Replacingthe fuse
To change the fuse, following the procedures below:

1. Remove the power cord from the back of the microscope

2. Locate the fuse compartment, which has a Fuse image. It is typically located beneath the
power connector.

3. Remove the fuse compartment. To do so, insert a flat head screw driver in between the
metal power tines and gently pry the fuse compartment loose with a slight down and out
motion.

4. Insert thee new fuse into the compartment, and then replace the fuse compartment back to
where it was originally.

5. Power up the microscope and test

Note: Fuse mayblowin order to protect internal damage to the microscope. And in most cases, replacing the fuse with the correct voltage will
resolve the issue. However, should you encounter a blown fuse frequently, please contact your distributor for further assistance.
