CX2 SERIES

Optics and performance outstanding in its class

1

Advanced optical and system performance
with excellent cost-efficiency

The evolution of this bestselling microscope delivers new,
cost-efficient improvements in both optics and system performance.
Newly equipped with Olympus' leading-edge UIS optical system,
it provides significantly enhanced image clarity in a variety of
observation methods, from brightfield to reflected light fluorescence.
For all inspection and training applications in the fields of biology
and medicine, the CX41 sets the pace for its class in both
basic and system performance.

Outstanding flat images from Plan C objectives

The CX41 provides images of outstanding brightness and clarity in a variety of observation
modes. As well as Olympus' renowned UIS optics infinity system, it employs the newly
developed PLC series of Plan Achromat objectives, which are made from carefully selected
top quality glass and manufactured with the most rigorous precision. The result is a major
improvement in image flatness, with the 10x and 40x objectives in particular providing images
that are among the very best in this class of microscope. Transmitted light illumination is
from a 6V, 30W high-intensity halogen light source.

Excellent cost-performance in reflected light fluorescence
and other observation methods

Dry darkfield condenser / CX-DCD

This dry-type darkfield condenser gives a
superior darkfield effect without the need for
immersion in oil.
Suitable for use
at 10x and 40x
magnifications.

Darkfield central stop / CH2-DS

For darkfield observations from 4x to 40x.

* Separate filter holder (CH2-FH) or attachment lens (CX-AL)
required.

Low magnification adapter /CX-LA

Use of the 2x low magnification objective allows
macro observation.

Simple phase contrast attachment /
CX-PH1, 2, 3

For phase-contrast observations at 10x,
40x and 100x.

Slide condenser / CX-SLC
Brightfield condenser / CH3-CD

These Abbe type condensers allow
brightfield observations from 4x to
100x. Accurate centering is provided
by the attachment lens (CX-AL) and the
iris diaphragm, to exclude unnecessary
light and obtain bright Koehler
illumination right across the
magnification range. These highly
economical condensers enable phase­contrast and darkfield observations by
simply adding basic accessories.

Reflected light fluorescence
attachment / CX-RFL-2

Users can swap between blue or green
excitation and transmitted light
observations. UIS optics provide bright
fluorescence images, with no intermediate
magnifications when changing from
transmitted light to fluorescence
observation. Standard PLC objectives can
be used without replacement.

Simple polarizing condenser /
CH3-CDP

With the optional plate adapter U-TAD,
polarizing observations from 4x to 100x
using a tint plate can be performed.
A U-GAN analyzer is provided for gout
inspection. Polarizing objectives from
4x to 100x are
available.

* Separate polarizer
U-POT and analyzer
U-ANT required.

Phase-contrast condenser / CX-PCD

The multi-purpose CX-PCD condenser
allows observation of brightfield, phase­contrast and darkfield images without
exchanging condensers. Phase-contrast
observation from
10x to 100x and
darkfield
observation from
10x to 40x is
allowed.

Dependable basic performance assures
outstanding operational convenience

Easy transportation and installation

The CX41 is eminently portable, with
convenient handgrips at the front and back
of the frame and no sudden, inconvenient
protrusion of the stage guide.

Move the specimen with just one finger

Rubber grips are provided for the stage
handles, allowing the specimen to be moved
smoothly with just one finger. The slim body
and conveniently positioned controls ensure
that everything is within easy reach, so
operators can maintain a natural posture.

Tilting binocular tube

The tilting binocular tube lets each operator
select the most suitable and comfortable
eyepoint — a valuable contribution to
reducing fatigue in extended observation
sessions.

Inward-facing quintuple revolving
nosepiece

The quintuple revolving nosepiece enables a
wide range of magnification observations
and various combinations of objectives.
Unrestricted access to the space in front of
the objective allows specimens to be
exchanged quickly and easily.

Torque adjustable focusing knob

The torque of the coarse focusing knob can
be adjusted, to suit different operators' needs
and to make focusing smooth and easy while
keeping the hands on the desk. A stage
upper limit stopper is also provided.

Rackless stage with enhanced operability

To keep the work area clear, and to avoid
interference with observation operations,
the X-direction travel guide does not extend
out from the side of the stage. The main and
sub scale displays are designed for easy
read-out.

Anti-fungus treatment

The treatment applied to the
observation tubes, eyepieces and
objectives, protects quality of optical
parts even in high humidity regions.

Trinocular tube / U-CTR30-2

Still digital (DP11) or video cameras can
be attached for on-site/remote illustration
of educational/discussion meetings.

Trinocular intermediate attachment /
U-TRU

A binocular tube on its own allows
photomicrography. Combination with
this intermediate attachment type
trinocular tube makes it possible to attach
photographic equipment and a video
camera at the same time.

Drawing attachment / U-DA

The drawing attachment projects an image
of the pencil and drawing surface into the
visual field.

More accessories, more observation versatility

Easy digital imaging

A simple eyepiece adapter enables an
Olympus digital camera to be attached to
binocular tube U-CBI30-2 — an easy,
practical and cost-efficient means of
obtaining digital images.

Arrow pointer / U-APT

Enables insertion of an LED arrow for
display in a photomicrograph.

2x magnification changer / U-ECA

Magnification is doubled by engaging the
auxiliary 2x lens.

Eyepoint adjuster / U-EPA2

Allows the eyepoint position to be raised by
30mm. Up to two eyepoint adjusters can
be attached between the frame arm and
observation tube.

U-DA

U-DAL10x

CX41+DP11

Dual observation attachment / U-DO3

Enables dual, simultaneous observation of
a single specimen from the same direction
with equal magnification and brightness for
both operators. A pointer can be used to
indicate specific sections of the specimen to
simplify the training process and promote
discussion.
