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 Leica 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.
The entire imaging system, including the zoom, objective and ErgoTube®,
is apochromatically corrected with much technological effort. Contrast,
sharpness, richness in detail, resolution, image and color fidelity are optimum. In addition, the patented illumination beam path guarantees at
every zoom level that light utilization is at a maximum and that fluorescence images are intensely luminous on a jet black background.
Though the reliability and robustness of Leica stereo microscopes is
legendary, like any high-tech product, the Leica 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!
Leica M Series User Manual The Leica M Series for Fluorescence 14
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 towards the observer.
Limits are made to be broken.
The Leica M205 FA is the world's first fluorescence 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 Leica M205 FA /
M205 FCA, 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 increase in performance benefits
your everyday work. Set up your specimens
on the microscope table with comfortable
freedom of movement and discover details in
stereo microscopy that you could never see
before.

Leica M Series User Manual The Leica M Series for Fluorescence 15
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 lineup. Optics carrier, stand, 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
diaphragm and more and transmits the information 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.
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 The Leica M Series for Fluorescence 16
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 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.
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.
Leica M Series User Manual The Leica M Series for Fluorescence 17
Leica engineers were careful to ensure that
the new Leica 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 Leica 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 Leica objective series. In this case, parfocality is no longer guaranteed.
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 have an
audible and tangible click to provide immediate feedback in case of accidental adjustment.

Depending on the work situation, it is
useful to restrict the maximum travel
path of the stereo microscope. This prevents
injury during handling of the sample caused
by fingers or hands becoming trapped or the
specimen touching the objective or even being
damaged by it.
Readjusting the motorized focus
The motorized focus is factory-adjusted and
normally does not need to be readjusted – even
if the maximum travel path is changed.
•
Exception: If the power fails while the
motorized focus is moving, the position
data are lost. In this case, the calibration must
be repeated using the Leica LAS software or the
Leica SmartTouch. To do so, please consult the
respective manual.
Restricting the bottom travel range
1. Move the motorized focus into the lowest
position you want to reach.
2. Unscrew the screw of the limit stop on the
side of the focusing column.
3. Push the limit stop to the height of the
motorized focus.
It is easiest to move the limit stop by keeping the screwdriver inserted and moving it
upwards.
4. Tighten the screw of the limit stop.

Objective Nosepiece – Assembly
Leica M Series User Manual Assembly 29
Objective Nosepiece – Adjusting Parfocality
The following procedure only has to be carried
out once. Afterwards, both objectives are parfocal, meaning that the specimen remains in
focus when the objective nosepiece is rotated.
This procedure must be repeated if you replace
either of the two objectives with another.
The following example assumes the combination of the 1× and 2× planapochromats. If
you are using another objective combination,
replace the 2× objective in the description with
the objective with the stronger magnification.
Preparation
O Open the iris diaphragm.
O Set the dioptric correction of the eyepieces
to "0".
Adjustment
1. Rotate the 2× objective into the beam path
