1.2 Safety instructions
Description
The Leica Z6 APO and Z16 APO are optical sys-
tems with 6.3:1 or 16:1 magnification changer and
a central beam path. The most precise information
can be obtained thanks to the parallax error free
observation. Measurements, adaptation tasks and
evaluations become more precise; more high-
quality information is obtained in photography and
image processing. The vertical beam path is virtu-
ally predestined for digital recordings with multifo-
cus programs. Polarized optical examinations pro-
vide true polarization colors, and the geometric
layers of flat, highly reflective objects such as
wafers appear without distortion when using
coaxial illumination.
A comprehensive range of modular accessories
such as objectives, carriers, video/phototubes,
stands, binocular tubes, eyepieces, etc. are avail-
able for the Leica Z6 APO and Z16 APO.
Permitted uses
With the Leica Z6 APO and Z16 APO zoom systems
and the apochromatic objectives, entire objects
can be inspected and documented without distor-
tion. As high-performance optical equipment, they
lend themselves to use with measurement and
testing systems including vision technology sys-
tems, and for high-end laboratory workstations.

8 Leica Z6 APO & Z16 APO – Safety concept
Health risks
Workplaces with optical systems facilitate
and improve the viewing task, but they also im-
pose high demands on the eyes and holding mus-
cles of the user. Depending on the duration of un-
interrupted 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 con-
sideration to ergonomic and organization
aspects.
The ergonomic optics concept and the design of
Leica optics systems aim to limit the strain on the
user to the lowest possible level. If you wish to
equip your zoom system with one of our binocular
tubes, we offer ErgoTubes®and ErgoModules®,
which compensate for the varying design heights
of the equipment, accessories and working dis-
tances, and for the variation of human height of its
users. If you have problems with the viewing con-
figuration, ask your Leica consultant for the most
ergonomic Leica solutions.
Direct contact with eyepieces is a potential
transmission method for bacterial and viral infec-
tions of the eye. Users should be made aware of
the potential risk of infection. The risk can be kept
to a minimum by using personal eyepieces for
each individual or detachable eyecups.
Repairs and servicing
– Only Leica Microsystems-trained service
technicians, or technical specialists assigned
by the person in charge of the instrument, are
permitted to carry out repairs.
– Only original Leica Microsystems spare parts
may be used.
– Unplug the power cable before opening voltage
carrying parts.
Touching the live circuit can cause injury.
Transport
– Use the original packaging for shipping or
transporting the zoom systems and their acces-
sory components.
– In order to prevent damage from vibrations,
disassemble all moving parts that (according to
the user manual) can be assembled by the cus-
tomer and pack them separately. These include
the objective, video/phototube, carrier, binocu-
lar tube, eyepieces, etc.
Integration in third-party products
When installing Leica products into third-party
products, note the following: The manufacturer of
the complete system or its dealer is responsible
for following all applicable safety instructions,
laws and guidelines.
