Introduction
With your purchase of an MT-10 series microscope
you have chosen for a quality product. The MT-10
type microscopes are developed for use at schools
and laboratories.
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.

Functions of the Microscope
The stand consists of a stand arm (C), stand base and an object stage (G).
Hold the microscope at the top of the
stand arm when it should be moved.
Tube
The 360 rotatable monocular tube is equipped with WF10x eyepiece (B).
Revolving nosepiece
The revolving nosepiece (D) can be equipped with 4 objectives (E).
Optical specications of the MT-30/MT-90 series range
The MT-10 series range microscopes are standard equipped with one wide eld eyepiece
WF10x (B) and achromatic objectives, as mentioned below in table 1

Table 1
The S40x, S60x and S100x objectives are equipped with a spring mount, to prevent damage
to the frontlens and the slide.
The Numeric Aperture - N.A. – of the objective is an indication for the resolving power of the
objective.

The total magnication can be calculated by multiplying the magnication of the eyepiece
with the magnication of the objective. The magnications are displayed in the table below:
Eyepiece Objective Magnication
10x 4x 40x
10x 10x 100x
10x 40x 400x
10x 60x 600x
10x 100x 1000x
Object stage
On the MT-10 series the slide is placed beneath the object clips. Focusing the specimen is
done by using the coaxial coarse- and ne adjustment knobs (H).
Coarse- and ne adjustment
The coarse- and ne adjustment knobs (H) for the height adjustment of the object stage
are mounted together on one axis (co-axial). On both ne adjustment knobs there is a
graduation with intervals of 0.002 mm. This can be used to measure depths in a specimen.
Abbe condenser with iris diaphragm
Beneath the object stage an Abbe condenser (L) N.A. 12.5 is mounted. The condenser can be
adjusted in height by means of turning or by a handle (polarization models). With this one
can focus the light on the specimen to optimise contrast-resolution ratio. The condenser is
factory pre-centered.
The iris diaphragm with lter holder is mounted beneath the condenser. The light intensity
can be adjusted by changing the exible opening.
Illumination MT-10 series
In order to have good color rendering against the Michel-Levy chart, the polarization
versions are standard equipped with a halogen illumination.
All other models have a LED illumination
The cable goes to the mains socket at the backside of the microsocpe.

Preparing the Microscope for Use
Remove the packing and put the microscope on a at
table. The objectives are pre mounted.
Put the plug into the mains supply and switch on the
microscope . Sit comfortably down behind the mi-
croscope and take a relaxed position while viewing
through the eyepiece (B).

INSTRUCTION MANUAL
Working with the Microscope
Please read the following instructions to achieve the best microscope observing results.
Setting the illumination
For optimum eect in contrast and resolution one should follow the below procedure:
Place a specimen on the object stage and focus using the 4x objective, with a fully opened
iris diaphragm.
• Turn the condenser in the highest position.
• Close the iris diaphragm, until it is just visible on the edge of the eld of view.
The microscope is properly set for use with the 4x objective. For each other magnication
this procedure should be repeated to ensure the best balance between contrast and
resolution.
Caution:
The maximum light intensity when using the 4x and 10x can damage the eyes!
When changing slides always start with the 4x objective again.
Safety device
To prevent damage to the objective lens, or breaking the slide, all types are equipped with a
pre-xed safety device (F).
It is recommended to use slides of 1.0 – 1.2 mm thickness in combination with cover glasses
of 0.13 mm or 0.17 mm thickness.

Use of the S100x oil-immersion objective
The MT-10 series microscopes are equipped with a S100x N.A. 1.25 oil immersion
objective. Please follow these instructions for using this objective:
• Focus the image with the S40x objective.
• Turn the revolving nosepiece so the S100x objective almost reaches the
click-stop.
• Put a small drop of immersion oil on the centre of the slide.
• Now turn the S100x objective so that you feel the click stop.
• The front lens is in contact with the immersion oil.
• Look through the eyepiece (B) and focus the image with the ne
adjustment knobs (I).
• The distance between the lens of the objective and the slide is only 0.14
mm!
• In case there are small bubbles visible turn the S100x objective a couple of
times left/right so that the front of the objective moves in the oil and the bubbles
will disappear.
• After using the S100x objective turn the ne adjustment knobs (I) up until
the front lens doesn’t touch the oil any longer.
• Always clean the front lens of the S100x objective with a piece of lens paper
that is moistened with a drop of xylol or alcohol.
• Clean the slide after use as well.
Caution
• Never put a drop of xylol or alcohol directly on the lens of the objective. It
could enter the objective and dissolve the glue that holds the lenses!
• Avoid oil contact with any of the other objectives!
