An eye for detail
Quality is not a question of luck
In the fields of quality assurance, damage analysis and education, expectations are high when it comes to instrumentation. A useful stereomicroscope must permit fast, precise determination of detail, deliver reliable results in
repeated inspections, ensure convenient, fatigue-free handling and provide options for a wide range of examination
methods and generation of digital data. The StereoZoom®Leica S8 APO will far exceed your expectations in many
regards.
Highest resolution
Normally, large apertures and high resolutions can only be attained in an optical system at the expense of depth
of field. With the Leica S8 APO, we have succeeded in combining a large aperture with a high depth of field and a
pronounced 3D image. Of all stereomicroscopes based on the Greenough principle, the Leica S8 APO with 10×/23
wide-field eyepieces delivers the highest values: unparalleled 70 microns depth of field, numerical aperture 0.1 NA,
resolution 300 Lp/mm, zoom 8:1, zoom range 10× to 80×.
The great depth of field simplifies working with tools and aids in the comprehension of interconnections without
frequent focal corrections.
Apochromatically explore the finest structural worlds
Leica S8 APO is the world’s only fully apochromatic, corrected Greenough stereomicroscope. The sophisticated
optical/zoom system renders the finest structural details with extreme sharpness and permits densely packed structures to be distinguished clearly. Non-corrected lens systems result in distracting color fringes and loss of detail in
fine structures. Together with apochromatic supplemental objectives 0.63×, 1.6×, 2×, the Leica S8 APO delivers peak
performance levels of up to 640× magnification and 600 Lp/mm resolution for highly efficient quality analyses of
surfaces, fractures, metal sections and transparent cuts.
The zoom range can be limited at both ends by stops at two user-defined magnifications. Inspections and experiments can thus be reproduced quickly and precisely under identical conditions.

Perfect 3D image for working on and nondestructive observing of whole objects
Stereomicroscopes enhance natural, three-dimensional vision and are indispensable in precision engineering, electronics and the plastics industry. Using Leica 10×/23 wide-field eyepieces, the upright, laterally correct fields of view
are 10% larger than with the eyepieces of other manufacturers. Users can observe and measure three-dimensional
components and their correct positioning in their entirety without time-consuming repositioning, apply tools and film
their work with ease. The 8:1 zoom permits the continuous enlargement of interesting details for thorough examination at high resolution.
Compact Greenough optical design
The optical system of the Leica S8 APO has two independent optical paths arranged at a 12° angle, each with its own
objective and eyepiece. As the objective pair is tightly spaced, the design of this stereomicroscope type is very slim
at the bottom. The advantages hereof are a clear view to the object field, unhindered access to the object and plenty
of room for tools. In the StereoZoom®Leica S8 APO, the optimally corrected center of the objective is used for imaging. This results in large, planar viewing fields with optimal chromatic correction and good contrast.
Patented ESD technology
The Leica S8 APO features antistatic material with a surface resistance of <1011Ohm/square cm. The patented
ZeroStat®polymer prevents the buildup of charges and reduces existing charges from 1000V to 100V in less than
2 seconds. Costly damage resulting from electrostatic discharge can thus be avoided during the assembly and quality assurance of sensitive electronic components such as printed circuit boards, integrated circuits and read heads.
A valuable side effect: ZeroStat®prevents the growth of mold, repels dust and dirt, and resists scratching and
peeling.
"Fault costs due to the inadequate quality of process results always arise when intermediate or final results are
rejected or require corrective processing. Customer complaints about quality not only result in warranty costs, but
also the cost of a lost customer and the potential damage to a company’s image arising from poor quality."

Success thanks to motivated employees
Ergonomics isn’t a buzzword for us, but a topic of fundamental importance in product development.
We take the entire human – his or her senses, locomotor system and brain – into consideration in
our fully integrated approach. Our goal is to ensure the interdependence of as many system elements as possible to guarantee the user’s comfort, concentration and efficiency. Leica ErgoDesign
TM
fully exploits the design and technical possibilities of modern optical manufacturing: innovative
technologies, quality optics, selected materials, ergonomic design, extremely precise workmanship
and tightest possible production tolerances.
Leica optics – objectively better
Your first look through the wide-field eyepieces will thrill you. See for your self how the
Leica S8 APO eases and enhances visual work – over long periods, without eyestrain. The combination of multiple-coated, corrected lens system and an ergonomic 38° viewing angle support natural viewing and a natural posture.
Ergonomic wide-field eyepieces
Leica’s 10×/23 wide-field eyepieces let you view 10% more of the object than comparable eyepieces
from other manufacturers. Orientation is easier, connections can be identified quickly without continuously moving the object, and the physical effort of visual accommodation is eliminated.
In the case of eyepieces for spectacle wearers, the exit pupil is 22mm in front of the eyepiece lens.
The additional space provides ergonomic advantages to users with and without spectacles.
Adjustable eyepieces provide eyesight correction over a range from + 5 to – 5 diopters. Soft, detachable eyecups block out distracting room light and help prevent eye infections (when using separate
eyecups for each user!).
"Almost all products can be copied within a matter of weeks, prices often within hours. The most diffi-
cult things to copy are competent, efficient employees and lasting customer relationships. People make
the difference! Not only your products, but also your employees and customers are strategic factors
central to your success and the sustainability of your business in the future."

Everything perfectly under control
The sophisticated design of the zoom and focus controls accommodates a comfortable hand position and supports natural eye-hand coordination. A practical feature: a single turn covers the entire
zoom range from the lowest to the highest magnification. The instrument will remain perfectly in
focus (parfocal) throughout the zoom operation, with no need for annoying corrections. State-ofthe-art technology with a patented magnetic assembly system, highly precise single-spindle design
and Delrin gearing guarantee that the zoom action will remain even, silky and precise even after
years of hard use.
Always in focus
The fine motor skills of the human hand are only effective if the hand is not called upon to exert an
appreciable amount of force. The ease of focusing can be adjusted individually to minimize the muscular effort required.
The Leica S8 APO remains precisely in its optical axis and stops at exactly the desired point when
focusing – it never moves by itself or loses the selected focal plane. The image even remains centered
when changing objectives and the instrument will still be at the same point of observation after focusing. This precise action offers the best preconditions for combining multiple images with different
focal planes to a complete image using the multifocus module of the Leica IM1000 image management
software (see page 11).
Ergonomics and more
Every person brings a different set of physical preconditions to the job, and every task places a specific set of demands on a stereomicroscope. In addition to the ergonomic advantages described
here, we offer a wide range of further options to optimize your workstation layout. Your Leica representative will be pleased to assist you in planning your workstations.
"The first step in investigating damage is to describe it. Details with regard to design and manufacturing are also of interest.
Next, the appearance, position and starting points of deformations, cracks, breaks, corrosion and wear must be recorded.
Documenting the damage with drawings and photographs is also useful." Institute for Materials Science,
