SZ61/SZ51

For Biological Use

Comfort at work: the key to consistent,
accurate results
User comfort has always been an Olympus priority. Even so, the standards set by the new SZ61 and SZ51 are

a revelation. The smoothly contoured finish, the newly designed "ComfortView" eyepiece, and the accessible,

responsive controls make operation easier and less fatiguing than ever before.

The compact design owes much to the incorporation of the Greenough optical system, which delivers

excellent flatness and ample depth of field as well as clarity, detail, accurate color and the least possible

distortion. Dependable, high-performance optics are central to the achievement of consistent, accurate

results in today's widening range of biological microscopy applications — as are ergonomic features which

make even long-duration tasks easier and less demanding to perform.

Welcome to the comfort zone.

Optical Performance

High-performance optics in a compact, comfortable design

Incorporating new improvements to the highly-regarded Greenough optical system, the SZ61 and
SZ51 successfully meet the demand for a variety of observation and documentation options in a
genuinely compact microscope design. Clear, sharp image reproduction is matched by new
ergonomic design elements which maximize comfort and ease of use.
The SZ61 and SZ51 microscope bodies are manufactured using newly developed lead-free optics,
demonstrating Olympus commitment to protect the environment.

6.7:1 —High zoom ratio

The SZ61’s class-leading magnification range extends from
6.7× through 45× (using 10× eyepieces), with a zoom ratio of
6.7:1. This derives from a newly developed optical system and
allows quick, comfortable observations at the most appropriate
magnification. The SZ51 provides a magnification range from 8×
through 40× (using 10× eyepieces), with a zoom ratio of 5:1.

Outstanding depth of field and flatness

The 10-degree angle of convergence in the Greenough optical
system secures excellent image flatness with large depth of
field.

High fidelity color reproduction

The careful selection of lens surface coatings and glass
materials in the entire optical system makes it possible to
observe and document specimen in their original, authentic
colors.

Sharp, clear, high-contrast images

High contrast images and field flatness ensure accurate
reproduction and documentation of original specimen shapes.

“ComfortView” eyepieces for greater comfort and

faster work
Quick, comfortable observation and documentation are ensured
by this completely new eyepiece design featuring Pupil
Aberration Control and Appropriate Positioning in the eye point.
The result is a field of view that is easy to find, comfortable to
view, and easy to keep.

The Greenough optical system has two zoom optical paths inclined at a 10° angle.
This enables a compact microscope design with high performance.

Five variations in zoom performance
The SZ61 and SZ51 provide five system configuration choices.
First, they can both be equipped with an ergonomically
designed 45° inclination tube when mounted on standard
stands. Second, operators can attach a 60° inclination tube
(SZ61-60/SZ51-60) for special applications where the zoom
body has to be tilted for use with other equipment or mounting
on a universal stand. And for documentation purposes,
Olympus also offers the SZ61TR, which incorporates a
trinocular tube for easy attachment of digital and video
cameras.

Convenient front-access operation

Improved ease of access to the most frequently used knobs
and controls maximizes operator comfort and reduces neck
and back strain.

The right accessory for every application

Digital camera DP22

The DP22 stand-alone digital camera for microscopes allows
easy observation, focusing, framing and saving while enabling
smooth, live image display of high-definition images for highly
professional presentations. The dedicated control box provides
smooth and intuitive operation via a touchscreen monitor or a
mouse (no PC required).
*DP22 digital camera is not for clinical diagnostic use.

Various universal stands

A variety of universal stands are available for the observation of
large size specimens. No matter how big the samples are or
how much they vary in size, Olympus has the right choice of
stands to suit any requirements.

Wide choice of auxiliary objectives and eyepieces
A wide choice of auxiliary objectives enables observation at the
optimum working distance (W.D.) for a variety of applications.
W.D. can be changed between 250 mm-350 mm (0.3×
objective) and 180 mm-250 mm (0.4× objective). Eyepieces are
available ranging from 10× to 30× to optimize system
magnification.
