Using comfortable and efficient routinesmicroscope
The CX43 and CX33 biological microscopes allow you to maintain comfort during prolonged routine observations. The microscope frame is always coordinated with your hands, and the position of the control knob is designed ergonomically to improve work efficiency. One hand can quickly place the sample with minimal movement, while the other hand can adjust focus and operate the stage simultaneously. The microscope also has a camera port that can be used for digital imaging.
Maintain comfortable observation conditions with small adjustments

CX33
Adopting LED lighting with stable color temperature
CX43/CX33 LED lighting combines multiple advantages such as immediacy and long lifespan:
Create daylight conditions to observe the natural colors of specimens
Consistent color temperature can be maintained at various brightness levels, thus avoiding the need to spend time adjusting brightness changes
With a lifespan of up to 60000 hours, the brightness remains stable at all times
Fixed Kohler lighting achieves comfortable observation experience
The fixed Kohler illumination used in CX43 and CX33 microscopes allows you to achieve the correct illumination effect without adjusting the spotlight.

Maintain comfort during long-term use

Ergonomically designed focusing knob
The low position design of the focusing knob allows you to maintain a comfortable posture of your hands and forearms on the table while observing. When observing at high magnification, the focusing limit device can prevent the specimen from accidentally hitting the objective lens.

Ergonomic stage and eyepiece position
The corresponding functions of CX43 and CX33 microscopes can provide support for your long-term laboratory work:
Low position design of the loading platform can improve comfort and alleviate fatigue
The visibility of the stage at the eye point position allows you to smoothly set up and inspect the specimen
The low position knob can be easily controlled with a light touch, allowing you to quickly and comfortably observe specimens
Excellent optical performance for obtaining flat images
The CX43 and CX33 microscopes can be used in conjunction with flat field achromatic objectives that provide clear images and high image flatness over a wide field of view. You can observe the specimen clearly through uniform illumination during routine observation.
*The CX43 is compatible with all UIS2 objectives, while the CX33 is equipped with a specially designed flat field achromatic objective.

Flexible and suitable for various applications
The standard universal spotlight used in CX43 microscope can achieve multiple observation methods:
bright field
dark field
Phase contrast
fluorescence
Simple polarization
You can change the magnification from 2x to 100x without moving the top lens on the spotlight.

Simple fluorescence observation
Fluorescence observation is simple and convenient. Insert the compact fluorescent lighting fixture into the microscope frame and place the spotlight dial in the FL position. The LED light source has been pre centered and has a lifespan of up to 60000 hours. By setting the spotlight dial to the FL position, transmissive lighting can be turned off, reducing background noise caused by incident light at the top of the spotlight.

Smooth magnification replacement
The rotating objective lens converter located at a lower height allows you to replace the objective lens while comfortably placing your elbows on a table.
When replacing samples or adding immersion oil, the inner facing objective converter can provide a larger workspace.

Supports up to five objective lenses
To improve flexibility, the rotating objective converter can support up to five UIS2 objectives. In addition to conventional objectives, you can also choose a 2x objective or a phase contrast objective for wide field observation.
Enhance contrast through simple aperture stop operation
Quickly enhance contrast by reducing the aperture stop. By adjusting the spotlight, this technology can obtain images of equal or even better quality.

Maintain corresponding contrast levels and observation settings
The CX43 microscope is equipped with two fixed pins that can help improve the observation workflow and reduce operational errors:
Use the fixed pin on the aperture stop to maintain the required contrast
If necessary, use the fixed pin on the spotlight to set the microscope for bright field observation

Sample holder that meets your observation method requirements
Multiple stage accessories that can help improve efficiency can be provided. When using a thin sample pad, there is no need to clamp the specimen with a specimen clamp. On the contrary, the specimen holder allows you to easily slide the slide onto the slide. The dual standard slide holder can accommodate one large sample or two standard sized glass slides.

Easily capture and view images using digital cameras and head up display systems
The wireless EP50 digital camera that supports LAN can easily share and display images among colleagues. Combining this camera with our CX series microscope can transform a regular laboratory into a digital laboratory. For group users, the head up display system can achieve easy viewing. Everyone can see the observed specimen in real time, without the need to take turns viewing through the eyepiece.
