SteREO Discovery.V8:
Enhanced Viewing
New high-performance optics – this is the outstanding
performance feature that Carl Zeiss has focused
on with the development of its latest entry level
model in the sophisticated stereomicroscope class.
The SteREO Discovery.V8 impresses with enhanced
resolution, increased contrast and, most notably, a
perceptibly improved stereoscopic impression. As a
result, it offers a image brilliance that is without equal
in this class of instrument. For a visible increase in
information in all biomedical and industrial applica-
tions, the time has come for a new view of things.

stereoscopic impression of the microscopic image.
Even on our SteREO Discovery.V8 entry level model.
Another area we focused on during practical realiza-
tion was the systematic minimization of stray light for
the entire optical system. For exceptionally brilliant
contrast and a new image quality with greater infor-
mation content.
The innovative simultaneous design process during
optical modeling has resulted in a standardized opti-
cal concept for all SteREO microscopes. For signifi-
cantly improved resolution and a perceptibly better
The Optical System: More Than
the Sum of its Individual Components
Today, anyone developing a stereomicroscope that
sets new standards with its optical system has to work
constructively at the very limits of physical feasibility,
taking full advantage of every new possibility offered
by state-of-the-art optical design. With experience and
innovativeness, you don’t have to look any further
than the optical systems from Carl Zeiss.
3 ranges of high-quality objectives
Achromat S: high-contrast images with a pronounced stereoscopic impression
Plan S: flat, distortion-free object fields
PlanApo S: precisely detailed resolution with no color fringes

The Illumination: Show Your
Specimen in a New Cold Light
Designed for slimline, space-saving light guides, opti-
mized for flicker-free live images on the monitor,
providing constant light output even if the line volt-
age fluctuates, and with ventilation as quiet as a
whisper – the high-intensity CL 1500 ECO cold light
The quality of the illumination – this is all-important
for contrasting in stereomicroscopy. The new fiber-
optic CL 1500 ECO cold light source with its wide
range of light guides and accessories offers you a
variety of opportunities for highlighting your struc-
tures perfectly.
The fiber-optic CL 1500 ECO cold light source
illuminates the specimen precisely with intensive
infrared-free light. Here with a twin-arm goose
neck for oblique reflected light with a targeted
shadow effect.

Reflected light with different light guides
a. Linear slit light for lateral grazing light
b. Fiber-optic annular slit illuminator for

c. Annular slit illuminator with polarization
filter device to minimize reflective glare
Objective: Plan S 1.0x
Magnification: 15x
Contrasts with variable optimization in brightfield, darkfield
and oblique light: the transmitted light equipment S
source outperforms conventional fiber-optic systems
thanks to several practical advantages, and offers
excellent performance at a superb price!
Incidentally, lamps and filters can be changed quick-
ly and conveniently. Even when stacked.

Or in a Completely Different
Light: With White LEDs
Each of the annular VisiLED illuminators is made up
of eight LED segments that can be switched variably.
A further advantage of noise-free light sources: up
Providing the ability to change rapidly from shadow-
free annular illumination to lateral oblique light, con-
trast optimization through turning of oblique light
around the specimen, continuous rotation of the illumi-
nation for a stereoscopic impression of the object in the
live image – and all this at the push of a button! The list
of new contrasting possibilities offered by the VisiLED
illumination system with its white LEDs is endless!
The VisiLED HCT contrast stage offers a wide range
of contrasts. It contains separate LED illuminators for
brightfield and darkfield, and sliders for finely adjusta-
ble oblique light. The LEDs are controlled using
the MC1500 multicontroller.

1. Interface with digital
image worlds: documentation
SteREO Discovery.V8 creates a connection for a variety of
digital photo and video cameras, via various phototubes, with
interface 60N. For the simple documentation of stereomicro-
scopic images, consumer cameras, with their good price/per-
formance ratio, are often recommended. Anyone wishing to
satisfy higher demands should use the high-resolution AxioCam
microscope cameras and the AxioVision imaging software
from Carl Zeiss.
2. Brilliant fluorescence: PentaFluar S 
PentaFluar S is the name of the retrofittable fluorescence equip-
ment for stereomicroscopes belonging to the SteREO Discovery
family. With up to five different filter blocks in the magazine
and special high-performance light sources, this is an outstand-
ing addition for contemporary fluorescence applications in
stereomicroscopy.
3. Better in position: the binocular
ergo-phototube S 5-45°
Ergonomics is also about choosing a relaxed sitting position when
operating a microscope. The viewing angle and height have to
coincide. The ergotube allows a free choice of viewing angle
between 5 and 45 degrees. Intermediate tubes and two working
positions for the eyepiece clamps vary the viewing height.
4. Vertical 2D impression:
the objective slide
A must for documentation with subsequent image analysis, e.g.
digital object measurements: the S/doc objective slide for the
SteREO Discovery family of microscopes. Positioned directly
beneath the zoom body, it enables the objective to be shifted
precisely under one of the stereoscopic beam path for a vertical
view of your specimen.
The Expandable Platform:
Flexible For a Variety of Applications
A typical feature of stereomicroscopes is their mod-
ular system design. Equipped with intelligent inter-
faces and fully integrated into the Carl Zeiss systems,
SteREO Discovery.V8, with its comprehensive range
of accessories, offers you a great deal of freedom in
terms of organizing your workplace to suit your own
practical needs.
