The Olympus CX21 series biological microscope is a new type of microscope that integrates biological teaching and clinical trials, and is the best-selling microscope in mainland China. Since entering the domestic market, this biological microscope has quickly sparked a wave of application in various famous universities. Peking University, Tsinghua University, China Agricultural University, and Beijing Union University have successively introduced this biological microscope and quickly applied it in teaching and experiments.

Since its launch, the Olympus CX21 series microscope has quickly gained popularity among students, mainly because this microscope is specially developed by the Olympus Group using advanced UIS2 optical system, suitable for student use. The UIS2 infinity correction optical system greatly improves the imaging quality of microscopes, while excellent image analysis judgment ensures the reliability and stability of microscope images in any situation.

The Olympus CX21 series microscope uses an Abbe condenser lens with bright field observation function. This type of spotlight has excellent focusing ability and perfectly optimizes the contrast of microscope imaging. When the markings on the aperture stop correspond to the magnification of the objective lens, it can increase the resolution and contrast of the image. The numerical aperture of the spotlight used in the CX21 series can reach 1.25 when immersed in oil, with a built-in aperture stop and a flat field chromatic aberration reduction effect. As for the eyepiece, the CX21 microscope uses 10 x and has a field of view of F.N. 18. When designing the observation tube, the microscope continued the common usage style of Olympus binocular microscopes, with a tube tilt angle of 30 degrees and a pupil spacing of 48-75mm. This design concept allows users to maintain a comfortable posture while observing. The observation tube also has the function of adjusting pupil distance and refractive power, which can be conveniently used by multiple people. The high field of view and high eye point eyepiece design make it easy for users to observe without taking off their glasses. The reflector is an optional accessory for Olympus microscopes, which adopts a configuration of 15 x eyepiece (F.N.12), making it convenient for users to continue observation even without power. When there is an external light source, the observation mirror can also be reversed and the slide can be observed through the large hole of the mirror arm, providing convenience for users.

Consistent with advanced optical systems, the flat field achromatic objective lens first appeared in the standard configuration of teaching microscopes, greatly improving the flatness of microscope images. This type of objective lens entering the teaching field can not only greatly improve the imaging quality of microscopes, autonomously compensate for image color differences, but also further correct the observation field curvature of the objective lens, making the image flatter and the brightness contrast clearer. Through this imaging, even in the most edge areas, the image and color can still remain complete and vivid. As for the perfect fixed 4-hole objective lens turntable, it maintains the convenience and smoothness during the use of the microscope, ensuring the smoothness and durability of the microscope during use, and providing convenience for the free conversion of the objective lens. In addition, there is a rubber ring on the objective lens turntable for easy conversion, which is also a contribution of Olympus ergonomics. In order to further meet the needs of different users, the manufacturer has specially developed four different models for consumers to choose from when manufacturing this CX21 series microscope. Including 4 x N.A.O.10 W.D. 22.0mm models; 10 × N.A.O.25 W.D. 10.5mm model; 40 × N.A.O.65 W.D. 0.56mm model; 100 × N.A.1.25 W.D. 0.13mm (optional) model.

Lighting is also an indispensable reason for the popularity of Olympus microscopes, and this CX21 microscope inherits Olympus microscopes' excellent lighting system. It uses a 6V20W high brightness halogen lamp as the power supply, which is compatible with 100-240V 50/60Hz. While ensuring bright and stable lighting, it perfectly extends the service life and safety of the bulb. The built-in transmitted light Kohler illumination overcomes the shortcomings of critical illumination, not only providing a bright and uniform illumination environment for the entire field of view, but also being the preferred choice for microscopic illumination.

The CX21 series stage uses a simple and durable frameless stage. A single specimen holder with dimensions of 120mm × 132mm and a range of motion of 76mm in the X-axis and 30mm in the Y-axis. The entire stage is driven by steel wire. Due to the use of a steel wire transmission unsupported platform, accidental injuries caused by bracket damage are largely avoided, and the wear-resistant design ensures the continuous and smooth movement of the platform. In terms of focusing design, the CX21 series microscope adopts a vertical movement of the stage, with a coarse adjustment stroke of 20mm per circle and a minimum fine adjustment distance of 2.5 microns. The coaxial coarse/fine adjustment knob allows users to operate freely on the left or right side, and the coarse adjustment tension can be determined according to the user's preferences. In addition, the distance between the focusing knob, lighting control knob, and stage handle is close, making it convenient for users to operate the microscope within a short distance. To avoid accidents during the focusing process, the microscope is designed with a stage focusing limit. After the focusing position is fixed, it makes it easier to refocus after replacing the specimen, and also avoids losses caused by accidental collisions between the objective lens and the slide.

To meet the needs of various types of consumers, the microscope has undergone full machine anti mold treatment, especially for sensitive parts such as optical components, which will not affect consumer use even in humid and hot southern regions. As for the solidification of the whole machine, it greatly reduces the probability of component damage during daily handling and use. The microscope is compact in size, with a height of only 391mm, and can be fully accommodated in a regular cabinet. In addition, the manufacturer has equipped a specialized wooden storage box (305 × 264 × 474) and a micrometer. Arrow indicators, filter holders, and dark field apertures facilitate various consumer needs.
