Comfortable, High-Throughput Routine Microscopy

CX43  biological microscopes enable you to remain comfortable during long periods of routine observation. The microscope frame conforms to your hands, and the location of the control knobs maximizes ergonomics to improve work efficiency. With minimal movement, you can quickly set a specimen with one hand, while adjusting the focus and operating the stage with the other hand. The microscopes can also feature an optional camera port for digital imaging.

Flexibility for Multiple Applications


The CX43 microscope uses a standard universal condenser, offering a variety of observation methods:

  • Brightfield


  • Darkfield
  • Phase contrast
  • Fluorescence
  • Simple polarization

You can change the magnification from 2X to 100X without moving the top lens on the condenser.





Accessories Simple polarizing intermediate attachment/CX3-KPA Offers polarized observation of urate crystals and amyloid in combination with a polarizer and analyzer.


Eyepoint adjuster/ U-EPA2 Raise the eyepoint position by 30 mm (1.2 in.) 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.

 Comfortable, High-Throughput Routine Microscopy

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 long 60,000-hour lifetime, helping reduce cost, and the brightness level remains stable throughout the LED’s life.

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 the 2X position.



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 during routine microscope observations.


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 using one hand.The specimen holder opens slightly and firmly retains the specimen during operation.The versatile holder accommodates various slide types, including a hemocytometer.





Use Up To Five Objectives

For added flexibility, up to five objectives can be mounted on the revolving nosepiece.Users can select different objectives, including a 2X objective for wide area observation or objectives for phase contrast.These objectives with long working distances help prevent specimen damage.


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.


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.



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.
