CX43 Biological Microscope

Comfortable, High-Throughput Routine Microscopy

The CX43 microscope enable users to remain comfortable during long periods of routine microscopy observations. The microscope frame conforms to the user’s hands and the location of the control knobs maximize ergonomics to improve work efficiency. Users can quickly set a specimen with one hand, while adjusting the focus and operating the stage with the other hand with minimal movement. The microscope also features an optional camera port for digital imaging.

Maintain Preferred Observation Conditions with Minimal Adjustments

Uniform Illumination with Consistent Color Temperature

The color temperature of the CX LED illumination produces daylight conditions, so specimens can be viewed with their natural colors. The color temperature is consistent at any brightness, so users don’t have to spend time making adjustments when they change brightness. The LEDs have a long 60,000-hour lifetime built into the design, helping reduce cost, and the brightness level remains stable throughout the LED’s life.

Excellent Optical Performance for Flat Images

The microscope employs Plan Achromat objectives, which provide clear images with high image flatness over a wide field of view. This helps users view specimens clearly and evenly illuminated during routine microscope observations.

Select and Set Your Contrast Level

Users can preserve their favorite contrast by locking the aperture diaphragm. It stays fixed at the optimally chosen position if it is accidentally touched while changing slides.

Change Magnification without Adjusting the Condenser

 Users can change the magnification from 4X to 100X without moving the top lens on the condenser. 2X magnification is also available by simply setting the objective and the condenser turret to 2X position.

Simple Fluorescence Observation

Fluorescence observation is simple and easy. Plug the compact fluorescent illuminator into the microscope frame for fluorescence observation. Its LED light source is pre-centered, and the transmitted illumination is shuttered by simply setting the condenser turret to the FL position. This reduces background noise in the fluorescence image from incidental light coming from the top lens of the condenser.

Remain Comfortable during Extended Usage

Single-Handed Sample Placement

A specimen can be quickly slid in and out with one hand. The specimen holder opens a little and firmly retains the specimen during operation. The versatile holder accommodates a variety of slide types, including a hemocytometer.

Smooth Magnification Change

The low-positioned revolving nosepiece enables users to quickly change magnifications with minimal arm movement between focusing, greatly improving work efficiency during prolonged use.

Use Up to Five Objectives

For added flexibility, up to five objectives can be supported by the revolving nosepiece. In addition to general objectives, users can select a 2X objective for wide area observation or objectives for phase contrast. These objectives with long working distances help keep specimens from getting damaged.

Ergonomically-Positioned Focus Knob

The low-positioned focusing knob enables users to make observations while keeping their hands and forearms rested on the desk, helping provide comfort. The focusing stopper prevents a specimen from accidentally hitting an objective when working under a high magnification.

Ergonomic Stage and Eyepiece Position

 The low-positioned stage is designed to enhance comfort and reduce fatigue. The stage surface can be widely seen from the eye point position, which enables users to smoothly set and check specimens on the stage. The stage knob can be controlled with just a light touch and can be adjusted at the same time as the focusing knob, since they are located close together.

Specimen Holders that Match Your Observation Style

Stage accessories improve efficiency when users need to observe a large number of specimens. With the specimen holder sheet, a specimen can be freely operated by a finger on the sheet and can be precisely adjusted using the stage knob. The double specimen holder can retain a large specimen or two specimens.

Simplified Fluorescence Observation

Fluorescence observation can be easily set up on the standard configuration while keeping the eye point the same as other observation methods. Simply plug the compact fluorescent illuminator into the back of the microscope frame.

Versatile Applications

The universal condenser offers a variety of observation methods and future upgradability. In combination with the five-position revolving nosepiece, multiple applications can be covered using the single microscope frame.



Phase Contrast



Simple polarizing intermediate attachment/CX3-KPA

Offers polarized observation of urate crystals and amyloid in combination with apolarizer and analyzer.

Eyepoint adjuster/ U-EPA2

Raise the eyepoint position by 30 mm for added comfort.

Arrow pointer/ U-APT

Insert an LED arrow into your image; great for digital imaging and presentations.

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 enhance discussion.
