Health risks
Workplaces equipped with stereomicroscopes
facilitate and improve the viewing task, but
they also impose high demands on the eyes
and holding muscles of the user. Depending
on the duration of uninterrupted work, asthenopia and musculoskeletal problems may
occur. For this reason, appropriate measures
for reduction of the workload must be taken:
optimal arrangement of workplace, work
assignments and work flow (changing tasks
frequently), thorough training of the personnel,
giving consideration to ergonomic and organizational aspects.
The ergonomic design and construction of the
Leica M stereomicroscopy series are intended to
reduce the exertion of the user to a minimum.
Direct contact with eyepieces can be a potential
transmission path for bacterial and viral infections of the eye.
The risk can be kept to a minimum by using
personal eyepieces for each individual or
detachable eyecups.
Leica M-series User Manual 6
Safety Regulations (cont'd.)
Light sources: safety regulations
Protective measures of the manufacturer:
★ UV protection screen in front of the speci-
men plane prevents the user from looking
directly into the UV rays.
★ Dummy filter carriers in the free positions
of the rapid filter changer prevent direct UV
radiation from reaching the eyes.
★ UV filters are installed in the observation
beam paths to protect the eyes.
★ The stray-light protection on the lamp
housing prevents irradiation of the hands.
Warning
★ UV radiation could damage the eyes.
Therefore:
★ Never look into the light spot on the speci-
men plane without a UV protection screen.
★ Never look into the eyepieces if no excita-
tion filter is in the beam path.
★ Fill empty filter positions with dummy filter
carriers (e.g. M165 FC).
★ Do not select a white, strongly reflective
background for the specimen.
Supply unit
Always unplug the supply unit from the power
supply:
★ When installing and disassembling the
lamp housing
★ Before opening the lamp housing
★ When replacing the high-pressure mercury
lamp and other parts, such as the heatabsorbing filter or the collector
★ During maintenance work on the supply
unit
Leica M-series User Manual 7
Safety Regulations (cont'd.)
Lamp housing
★ Never open the lamp housing while the
lamp is switched on. Risk of explosion, UV
exposure, blinding!
★ Before opening the lamp housing, allow it
to cool off for at least 15 minutes. Danger
of explosion!
★ Never cover the air duct on the lamp hous-
ing. Danger of fire!
Mercury lamp
★ Follow the user manual and safety regula-
tions provided by the lamp manufacturer,
and, in particular, the section on how to
proceed if a lamp breaks and releases
mercury.
★ For transport, remove the mercury lamp,
transport it in its original packaging and
protect moving parts in the lamp housing
using the transport anchors.
★ When it has reached the end of its rated life
(follow the manufacturer's specifications
and the minute meter on the supply unit).
★ To minimize the risk of explosion, replace a
discolored mercury lamp promptly.
★ Leica Microsystems assumes no liability
for damage caused by exploding, incorrectly installed or improperly used mercury
lamps.

Congratulations!
The New Leica M Series
The introduction of the LeicaM50, M60 and M80 adds three new highquality routine stereomicroscopes to the proven M-Series range from
Leica Microsystems. The optical brilliance and the wide range of accessories make them the ideal microscope for quality assurance and similar
industrial applications.
Magnification in stages or zoom
The LeicaM50 stereomicroscope includes precisely reproducible magnification levels for repeated examinations, measurements, drawing or
photography of objects under absolutely identical conditions. The five
easily selectable positions can be set without removing the eyes from the
eyepieces. This ensures that your results remain comparable at all times
without great efforts.
The Leica M60 and M80 stereomicroscopes can be used for a wide range of
routine applications with the 6:1 / 8:1 zoom and switchable ratchet steps.
The large working distance and the brilliant imaging power shows you
the finest details of your specimens without losing your overview of large
workpieces.
Common to all microscopes is the Leica range of accessories. Whether you
need a variety of illumination types, a wide selection of objectives or the
Leica swinging-arm system – there is a solution for everything there!
Do you already own stereomicroscopic equipment and are thinking of
switching to Leica? No problem! LeicaM50, M60 and M80 fit into microscope carrier with a diameter of 76mm and are therefore compatible with
many suppliers. You can simply continue to use your components and add
the proven Leica stereomicroscopes.
Leica M-series User Manual 12
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.
Have a special request? Let us know!
Leica Microsystems enjoys an exceptional reputation when it comes to devising customer-
specific 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.
Leica M-series User Manual 13
Maximum Compatibility
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 objectives of this new generation have the
same reference focal length as the objectives of
the MZ generation. If you prefer, you can therefore continue to use the previous Leica objective series.
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
The new M-series eyepieces have an audible
and tangible click to provide immediate feedback in case of accidental adjustment.

Base and Focusing Column
The first step is to connect the focusing column
of the M series to the corresponding base.
Tools used
★ Hex socket screwdriver, 3mm
Assembling the column adapter
1. Remove the three screws provided from the
column.
2. Install the base on the column using the
three screws.
Tip: Place the column on the edge of a table to
attach the base and have another person help
you.
Leica M-series User Manual 17
Microscope Carrier
Tools
★ Allen screwdriver provided
Assembly
The microscope carrier is fastened to the column
using the screw provided.
Alternative installation options
Depending on the desired working distance, the
microscope carrier can be installed in the standard way or upside down (see figure below).
Leica M-series User Manual 18
Optics Carrier
Tools used
★ None
Assembling the optics carrier
1. Unscrew the clamping screw on the holder
for the optics carrier.
2. Place the optics carrier into the holder and
align it in such a way that the notch in the
optics carrier and the bottom clamping
screw are on top of each other.
2. Tighten the clamping screw below the
optics carrier.
Leica M-series User Manual 19
Tube
All intermediate tubes that fit between the
optics carrier and the binocular tube are fitted
in the same manner.
Tools used
★ No tools required.
Preparation
1. Unscrew the positioning screw and remove
the protective cover.
Assembling the tube
2. Push the tube (for example, the inclined
binocular tube) into the dovetail ring and
rotate it slightly in both directions until the
positioning screw meshes with the guide
groove.
3. While holding the tube only slightly, carefully tighten the positioning screw. It
is automatically brought to the correct
position.
