1.0 Introduction
With your purchase of a FUTURO BZS stereo microscope you have chosen for a quality product.
The microscope is especially eveloped for use at schools, and by collectors of minerals, stamps
etc.
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.

4.3 Focusing
With the focusing knobs (F) the object can be sharply focussed.
4.4 Magnification adjustment
The zoom stereo microscopes is equipped with 2 achromatic zoom objectives. By using the zoom
knobs (D) the magnification can be adjusted in a smooth, stepless way.
5.0 Preparing the (zoom) stereo microscope for use
Take the stereo microscope out of its packing and put it on a firm stable table. Please make sure
that the horizontal arm (J) is pulled out only to the extent, that the stereo microscope always has a
safe and steady standing position and does not tip over. Place the eyeshades onto the eyepieces.
Sit comfortably down behind the microscope and take a relaxed position while viewing through the
eyepieces (A).

6.0 Working with the stereo microscope
Set the focusing (F) on neutral position.
Place an object onto the working space and adjust the height of the horizontal arm (J) until
you have a passably sharp image , than fix the height of horizontal arm (J) by the locking
knob (N).
Set the diopter correction (B) of both eyepieces in the neutral position (marking notch on
tube)
Adjust the interpupillary distance by moving both prism housings (C) towards each other
until one round image is seen with both eyes.
6.1 Setting the eyepieces in order to have a sharp image over the complete zoom range
Set the magnification at the highest position by means of the zoom knob (D) and sharply
focus on a flat specimen.
Now bring the magnification down to the lowest position.
First correct the sharpness with only the left hand diopter correction (B), and than for the
right hand one.
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.
