STEREO MICROSCOPES
EDUBLUE SERIES
1.0 Introduction
With your purchase of a EUROMEX EduBlue range stereo microscope you have chosen for a
quality product. The EUROMEX EduBlue range microscopes are developed for use at schools
and laboratories.
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.

4.0 Functions of the stereo microscope
The stereo microscope consists of a stand (G) with object stage, a vertical pillar (ED.xxxx-P
models) or rack and pinion stand (ED.xxxx-S models) and a head with focusing system.

4.2 Optical specifications
The ED.1302-P and ED.1302-S models are equipped with paired widefield 10x eyepieces (N) and
a pair of achromatic 1x/3x objectives mounted in one revolving nosepiece.
The ED.1402-P, ED.1402-S and ED.1405-S models are equipped with paired widefield 10x
eyepieces (N) and a pair of achromatic 2x/4x objectives mounted in one revolving nosepiece.
The ED.1502-S model is equipped with paired widefield 10x eyepieces (N) and three achromatic
1x/2x/3x objectives mounted in one revolving nosepiece.
The ED.1802-S and ED.1805-S models are equipped with paired widefield 10x eyepieces (N) and
three achromatic 1x/2x/4x objectives mounted in one revolving nosepiece.
Total magnification is calculated by multiplying the magnification of the eyepieces with the
magnification of the objectives. The eyepieces are locked in the tubes by means of a small screw.

4.3 Object stage
The EduBlue stereomicroscopes are equipped with an transparent object stage and 2 object clips.
All models have a transmitted and a incident LED illumination.
4.4 Safety device
The fixing screw (P) locks the stand arm into its position. When loosening the fixing screw, one can
adjust the holder in height depending of the volume/height of the object. After adjustment the fixing
screw (P) should be tightened again and the safety device (O) repositioned and secured in order to
avoid that the arm stand can fall down unexpectedly !
4.5 Focusing
With the focusing knobs (K) the object can be sharply focussed.
The working distance (distance between front of objectives to top of object) is about 60 mm.
4.6a Revolver of Dual Magnification models
The ED.1302-P / ED.1302-S / ED.1402-P / ED.1403-S and ED.1405-S are equipped with 2 pairs
of achromatic objectives mounted in one revolver (objective changer). By turning this nosepiece
another magnification is set. Turn the nosepiece untill it clearly “clicks” into position.
4.6b Revolver of Triple Magnification models
The ED.1502-S / ED.1802-S and ED.1805-S are equipped with 3 pairs of achromatic objectives
mounted in one revolver (objective changer). By turning this nosepiece another magnification is
set. Turn the nosepiece untill it clearly “clicks” into position.
4.7 Illumination
All models have a transmitted (diascopic) and incident LED illumination
With use of the potentiometer switch (D) the illuminators can be adjusted in intensity and both
illuminations can be used simultaneously.
With the switch (I) the illuminations can be switch IN and OUT
4.8 Tension adjustment
When the system lowers itself by its own weight, the tension of the focusing knob (K) should be
adjusted. This is done by turning the two focusing knobs in opposite (clockwise or
counterclockwise) directions
5.0 Preparing the stereo microscope for use
Take the stereo microscope out of its packing and put it on a firm stable table
Insert the plug of the power supply adapter into the mains supply and switch on the illumination
with the On/off switch (I) and place the eyeshades onto the eyepieces. Sit comfortably down
behind the microscope and take a relaxed position while viewing through the eyepiece (N).

6.0 Working with the stereo microscope
• Place an object onto the object plate and adjust the height of the holder randomly with the
screw (P) at the backside of the stand.
• Adjust the interpupillary distance by moving both prism housings (M) towards each other
until one round image is seen with both eyes.
• Focus the specimen by means of the focusing knobs (K) on both sides of the holder.
• For normal observation both tubes should have the same length, but to adjust any
difference between the two eyes, proceed as follows: focus sharply on a flat specimen, only
using the right eye, looking through the right eyepiece. Now look through the left eyepiece,
only with the left eye and focus the specimen with the diopter adjustment ring on the left
tube.
7.0 Maintenance and cleaning
Always place the dustcover over the microscope after use. Keep the eyepieces always mounted in
the tubes to avoid dust entering the instrument.
7.1 Cleaning the optics
When the eyepiece lens is dirty it can be cleaned by wiping a piece of lens paper over the surface
(circular movements). When this does not help put a drop of xylol or alcohol on the lens paper.
Never put xylol or alcohol directly on the lens!
When dirt is clearly visible in the field of view it resides on the lowest lens of the eyepiece. By
using the Allen-key the eyepiece can be removed from the tube. Clean the outside of the lens.
In case there is still dust visible please check if the dust is in the eyepiece by turning it. If this is the
case remove the lowest lens carefully from the eyepiece and clean it.
Caution
• Cleaning cloths containing plastic fibres can damage the coating of the lenses!
7.2 Maintenance of the stand
Dust can be removed with a brush. In case the stand or stage plate is really dirty the surface can
be cleaned with a non-aggressive cleaning product.

7.3 Charging the batteries
At first use, the batteries should be charged. Connect the cable of the charger to the inlet at the
back side of the microscope base, and connect the charger to the mains supply. The first charging
will take about 20 hours to reach full capacity.
7.4 Exchanging the batteries
Caution: Always remove the power adapter from the mains supply
before changing the bulb!
• Remove the battery compartment cover from the bottom plate.
• Replace the 3 batteries (AA type) in the correct order and place the battery cover back again.
