Congratulations!
Congratulations on obtaining your new Leica M series stereo microscope.
We are convinced it will exceed your expectations, as never before have
we applied our decades of experience in the areas of optics, mechanical
engineering and ergonomics in such an uncompromising manner.
The M series embodies all the qualities you associate with the name Leica
Microsystems: excellent objectives, high-quality engineering, and reliability. Furthermore, the modular design ensures that the M series adapts
perfectly to your needs – no matter which accessories you require for your
tasks.
Leica M Series User Manual
Though the reliability and robustness of Leica stereo microscopes is
legendary, like any high-tech product, the M series requires a certain
degree of care and attention. Therefore, we recommend that you read
this manual. It contains all the information you need regarding operation,
safety and maintenance. Simply observing a few guidelines will ensure
that even after years of intensive use, your stereo microscope will continue
to work as smoothly and reliably as on the very first day.
We wish you the best of success in your work – after all, you are now
equipped with the best tool!
The Leica M Series13
A Step Towards Infinity
Ever since their introduction by Horatio S.
Greenough, stereo microscopes have worked
according to the optical principles based
primarily on Ernst Abbe's research. For over a
century, ingenious optics designers and engineers have worked to push magnification, resolution and image fidelity to the limit permitted
by optics.
In doing so, they have always been constrained
by the interrelation between three factors: the
higher a microscope's resolution, the lower the
available working distance. If one increases the
distance of the optical axes, the three-dimensional image seen by the observer becomes
distorted – a sphere becomes an ellipse, a flat
surface curves toward the observer.
Limits are made to be broken.
The Leica M205 C is the world's first stereo
microscope with a zoom range of 20.5:1. This
accomplishment, however, was not enough for
Leica's engineers. With the new FusionOptic in
the M205 C, they have succeeded in going yet
another step beyond previous limits. In addition
to the increase in magnification, the resolution,
too, has been increased to up to 1,050 lp / mm*,
which corresponds to a resolved structure size
of 472 nm.
Of course, this performance increase benefits
your everyday work. Set up your specimens
on the microscope with comfortable freedom
of movement and discover details in stereo
microscopy that you could never see before.

The Electronics: Comfort, Convenience and Safety for Your Experiments
Never before have electronics been used as
extensively in a Leica series as in the new
M series. Optics carrier, tripod, base and illuminator are all connected using electrical contacts –
which provides a number of advantages.
Reliability for your experiments
Exact reproducibility of results is an increasingly common demand, particularly in research
and development. The continuous encoding
captures parameters such as the magnification, the illumination, the position of the iris
Contacts not only transmit data, but also supply
the power.
Leica Application Suite (LAS) evaluates the
transmitted data and can restore the test
situation later.
Leica M Series User Manual
diaphragm and more to the Leica LAS software.
Thus you always know the conditions under
which an image was acquired.
Fewer cables
A large part of the cables have been routed in
the interior of the column. Data are also transferred via the interface between the column,
the optics carrier and the carrier. The direct
result is that you need fewer cables – this not
only makes your workstation neater and more
comfortable, it even makes it appear larger.
The Leica M Series15
The Modular Design: Everything is Relative
The Leica M series provides maximum flexibility in choosing equipment, thanks primarily to
the modular configuration and the compatibility that Leica has painstakingly maintained for
decades. The optics carriers, eyepieces, bases
and more can be combined in any way you
choose, allowing you to create the microscope
that best suits your needs.
Leica M Series User Manual
Despite this, you will notice that the controls
and individual components do not differ significantly. Whichever configuration you choose,
you will quickly feel right at home.
Have a special request? Let us know!
Leica Microsystems enjoys an exceptional reputation when it comes to devising customerspecific solutions. If you have a special request
that cannot be met with standard parts, contact
your Leica consultant. We have a solution for
every problem.
The Leica M Series16
Maximum Compatibility
Leica engineers were careful to ensure that the
new M series – like its predecessors – remains
compatible with existing series. This means
that objectives, bases, tubes and so on can be
reused.
Objectives
All new objectives of the M series are parfocal,
meaning that when used with the objective
nosepiece, they can be replaced while keeping
the specimen in perfect focus.
If you prefer, you can continue to use the previous objective series. In this case, parfocality is
no longer guaranteed.
Leica M Series User Manual
Tubes
The interface between the optics carrier and
the tube has remained the same, so existing tubes fit the new M series. The new tubes
are designed for eyepieces with field number
23, while the predecessor models were only
designed for field number 21, resulting in a
smaller object field.
Eyepieces
However, the new M-series eyepieces models
have an audible and tangible click to provide
immediate feedback in case of accidental
adjustment.

For most microscope users, digital documentation has become an invaluable part of their
work. Research results can be presented in an
attractive manner; measurements on the digital image provide clarity and, in conjunction
with the motorized IsoPro cross-stage, even
images of large specimens can be captured
step by step and automatically joined to create
a new complete image.
Leica cameras
However, if you require absolute control
over the camera and need the capability for
measurement, evaluation and more in addition
to photography, the digital Leica cameras are
exactly right for you. Together with the Leica
Application Suite, they provide virtually limitless freedom of use. For additional information about Leica cameras, refer to the camera's
documentation.
Leica Application Suite
The "Leica Application Suite", or "LAS" for
short, is, as it were, the digital extension of the
Leica M series microscopes. In addition to
capturing images, it lets you control the microscope, illuminator, stages, cameras and more.
For additional information, refer to the LAS
online help.
Adapter
If camera control using the Leica Application
Suite is not required, conventional mirror reflex
and rangefinder cameras from third-party
manufacturers can be used. For this purpose,
Leica Microsystems offers a variety of adapters
that can be used together with the 50 % and
100 % trinocular tubes.
Leica M Series User Manual
Photography & Video73
Photo Tubes and C-mounts
Application
All Leica DFC/DMC/MC cameras are equipped
with a standardized C-mount interface. In turn,
the C-mount adapter for the respective trinocular tube is connected to this interface. This
adapter creates a solid mechanical connection between the microscope and camera and
ensures optimum rendering of the microscopic
image on the image sensor of the camera.
Usually, the ideal is for the digital camera to
capture as much of the field of vision as possible, while excluding as much of the black edge
of the field of vision as possible. To do so, the
magnification factor of the C-mount adapter
must match the image format of the sensor as
closely as possible (see table).
If there is unwanted shading at the corners even
with a compatible C-mount adapter installed, it
can be corrected using the "Shading function"
of the camera software.
Alternatively, you can also use a C-mount
adapter with higher magnification. This primarily avoids the critical border area of the field of
vision and concentrates on the center of the
field of vision.
Cameras from third-party suppliers
In addition to Leica cameras with the standardized C-mount interfaces, you can connect thirdparty cameras to the microscope using a T2
bayonet adapter.

The Microscope Carrier AX
Users who intend to do a great deal of photography, take measurements or work with polarization should select the microscope carrier AX
for stereoscopic/axial observation. The parallax-free imaging by means of a perpendicular
beam path leads to results without parallax
error.
Stereoscopic viewing
A stereoscopic view is required for examining
spatial objects. For this purpose, the microscope carrier AX must be brought to its home
position.
1. Unscrew the clamping screw.
Compatibility
The planachromatic and planapochromatic
objectives fit into the thread in the microscope
carrier AX for the Leica M125 C, Leica 165 C and
the Leica M205 C.
2. Push the microscope into the home position (mid position) to obtain a spatial view
and tighten the clamping screw.

Microscope Carrier78
The Microscope Carrier AX (Continued)
Parallax-free images
The parallax-free imaging produces more
precise results in photography, measuring and
polarization.
1. Unscrew the clamping screw.
2. Push the microscope towards the left as
far as it will go and tighten the clamping
screw.
Leica M Series User Manual
The objective is now located directly beneath
either the left or the right beam path.
Coaxial light and the Leica M205 C
When using coaxial incident light together with
the Leica M205 C, unscrew the clamping screw
and press the optics carrier towards the right
(caution: the movement is only 2 mm). This
provides uniform light intensity in both beam
paths.
Microscope Carrier79
The Objective Nosepiece
Use
The objective nosepiece enables you to switch
between two objectives using just one hand
movement, for example between a 1× and a 2×
planapochromat.
Parfocal work
With the new M series objectives, the parfocality is maintained even when objectives are
changed, meaning that the specimen remains
in sharp focus during the change.
Technical constraints
The objective nosepiece cannot be
used together with the LED5000 MCI
system illumination, as the objective nosepiece
can no longer be rotated.

The Different Types of Objectives
To meet the various requirements regarding
imaging properties, there is a choice of highquality interchangeable planachromatic and
planapochromatic objectives and also lowerpriced interchangeable achromatic objectives.
OO
Achromatic objectives are particularly
suited for specimens with high-contrast
structures.
OO
Flat-field (planachromatic) objectives are
particularly well suited for studying flat
objects such as wafers and thin sections.
OO
With planapochromatic objectives, the
finest structures are visible with high
contrast. The sophisticated apochromatic
correction allows these objectives to attain
the highest color brilliance and fidelity.
Leica M Series User Manual
Achromatic objectives
The 0.32×, 0.5×, 0.63×, 0.8×, 1×, 1.5×, 2×
achromatic objectives offer countless variants
for selecting the object field diameter, magnification ranges and working distances (see
page 120).
Achromatic objectives with a long focal
length:
For special applications achromatic objectives
with long working distances and focal lengths
of f=100 mm to 400 mm are available.
Planachromatic objective 1×
For the highest requirements for overall image
quality, we recommend equipping the microscope with the 1× plan (flat-field) objective,
which returns sharp, contrast-rich object fields.

Leica TL RCI: The Deflection Mirror
1
Inverted world?
Depending on the properties of the specimen
(refractive index of the environment) and the
perception of the viewer, it is possible that
the switches described below for positive and
inverted relief contrast are to be operated
in reverse. This means that the lower switch,
rather than of the upper switch, controls
inverted relief contrast and vice-versa.
Leica M Series User Manual
Tilted mirror
The built-in mirror features one flat and one
concave side and can be rotated and moved.
The concave side has been specially designed
for the optical requirements of objectives with
a high numerical aperture. The black rotary
knob on the left side of the transmitted-light
base can be used to rotate the built-in pathfolding mirror and move it forwards/back.
Functions of the rotary knob
The rotary knob (1) fulfills the following tasks:
The concave cutout on the handle indicates the
concave side of the mirror, allowing intuitive
operation at any time without eye contact.
OO
Turning the deflection mirror from the flat
to the concave side.
OO
Slight tilting to guide the light beam
through the specimen plane at a steeper or
flatter angle
OO
Moving the deflection mirror (forwards/
back)
The angle of light incidence in the specimen
plane changes depending on the tilt and
position of the mirror. As a result, switching
between transmitted light bright field, oblique
illumination and dark field-like illumination is
possible.

Leica TL RC / Leica TL RCI: Operation
Setting the relief contrast
The two switches on the left side of the transmitted-light base TL RC/TL RCI activate two
built-in flaps. The outer switch (1) controls the
inverted relief contrast, and the inner switch (2)
adjusts the positive relief contrast.
1
2
Depending on the flap position, a part of
the opening of the built-in Fresnel lenses are
covered, which results in the different contrast
effects. Phase structures typically act as spatial,
relief-type images – in the positive relief
contrast like hills, in the inverted relief contrast
like valleys.
Increased contrast without relief is attained
if both diaphragms are set to 45°. A gap-like
illuminated area is created. By tilting the deflection mirror slightly, you can move the gap over
the entire field of view and quickly toggle
between positive and negative relief images.
The dynamic effect makes it easy to distinguish
phase structures from amplitude structures.

Leica TL RCI: Methods in Transmitted Light
Vertical bright-field illumination
Suitable for stained amplitude specimens with
sufficient contrast.
The light beams are deflected vertically through
the specimen. This results in an accurate bright
field with maximum brightness.
Leica M Series User Manual
Inclined transmitted light
Suitable for semitransparent, opaque specimens such as foraminifera and fish eggs. Move
the deflection mirror until the desired data are
visible.
Single-sided dark field
Suitable for fixed specimens and fine structures.
The flatter the angle at which the light beams
are deflected into the specimen plane, the
darker the substrate appears. A dark field-like
transmitted light is created. Outlines, fine edges
and structures are bright, in contrast with the
dark background, through diffraction of the
light beams on the dark background.

Leica TL RCI: Relief Images
Starting position
1. Push the deflection mirror all the way back
towards the column.
2. Turn the deflection mirror into the notch
position at an angle of 45°.
Leica M Series User Manual
Positive relief contrast
Suitable for semitransparent and transparent
specimens. The phase structures look like hills.
The effect can be strengthened or weakened by
gently tilting the deflection mirror.
Negative relief contrast
Suitable for semitransparent and transparent
specimens. These settings result in a negative
relief contrast. Phase structures look like valleys.
The effect can be strengthened or weakened by
gently tilting the deflection mirror.
Bases94
Leica TL RCI: Relief Images (Continued)
Dynamic relief contrast
Suitable for semitransparent and transparent
specimens.
By tilting the deflection mirror slightly, you can
move the gaps over the entire field of view and
quickly toggle between positive and negative
relief images. The dynamic effect makes it easy
to distinguish phase structures from amplitude
structures.

Constraints
The relief methods provide good results from
mid-zoom to high magnifications and with 1×,
1.6× and 2× magnifications. In the lower zoom
half and with weaker specimens, the object

Example
MO
Magnification of objective
MO
1× objective
ME
Magnification of eyepiece
ME
25×/9.5 eyepiece
z
Magnification changer position
z
Zoom position 4
q
Tube factor, e.g. 1.5× for coaxial incident light, 1.6× for 45°
ErgoTube
q
Coaxial reflected light 1.5×, tube factor
r
Factor 1.25×
r
Factor 1.25x if the planachromatic and planapochromatic
objectives of the MZ125/MZ16 are used on the MS5, MZ6,
MZ75 or MZ95
NFOV
Field number of the eyepiece. Field numbers are printed on the
eyepieces: 10× = 21, 16× = 14, 25× = 9.5, 40× = 6.
Calculation example: magnification in binocular tube
MTOT VIS = MO × ME × z × q × r
