The all-new RX50 research grade upright biological microscope gathers years of research and development achievements and technological wisdom in the field of microscopic optics. With a core design philosophy of wholeheartedly pursuing safe, comfortable, and efficient user experience, the innovative product features humanized design. The system combines modular functions, high-definition optical images, and simple operating mechanisms to easily achieve various professional observations and diagnostic analyses such as bright field and fluorescence, fully meeting the needs of users in scientific research, medical and other fields.
The quality certification system that the product has passed:

Large platform with left and right hand positions:
The new stage adopts a bidirectional track transmission mechanism, which completely solves the safety hazards caused by the protruding transverse guide rails of traditional platforms, and plays an overload protection role at the end of the bidirectional stroke, improving the reliability of the mechanism. Meanwhile, the wire rail transmission technology brings a more comfortable operating experience. The adjustment handle of the loading platform can be installed on either side of the platform according to customer needs to suit different customer preferences. The ergonomic design of low hand position, X and Y dual axis adjustment makes it easy to achieve humanized and stress free operation, improving work comfort. Adopting a damping double slice clamp, it can simultaneously clamp two slices for rapid comparative analysis, with a movement range of 80mmX55mm. Precision of 0.1mm. The surface of the stage is treated with a special surface treatment process to prevent corrosion and wear. The circular arc transition design around the platform reduces stress concentration while preventing damage caused by collisions. Light blocking film is available for selection, which can effectively reduce the interference of stray light in the transmission direction during the observation of reflected fluorescence, and improve the image contrast.
◆ Modular body to improve system compatibility:
The RX50 biological rack adopts a modular structure design, with the cross arm separated from the microscope body, thus achieving compatibility with biological/fluorescent rack systems and allowing for more freedom in selection. The new type of high-sensitivity coarse and fine adjustment coaxial focusing mechanism adopts a two-stage transmission of coarse and fine adjustment, with a tension adjustment device and a random upper limit device. The weight of the coarse adjustment mechanism can be adjusted by itself, and any position can be set as the upper limit of the coarse adjustment. The coarse adjustment stroke is 25mm, and the fine adjustment accuracy is improved to 1 μ m. The high-sensitivity fine adjustment mechanism can not only perform precise focusing, but also serve as a precision measurement.
Multi level spectral ratio observation head design:
The all-new RX50 series observation tube adopts a wide beam imaging system design, supporting the world's leading 26.5mm ultra wide field of view observation, bringing you a new experience of large field of view. Three level hinged three eye observation tube, with 100% imaging light used for binocular observation or three eye photography, an additional 20% for binocular observation and 80% for microscopic photography, making it convenient for users to compare and observe images under the microscope and video images simultaneously. The two-stage positive image hinge three eye observation tube ensures that the direction of sample movement is consistent with the direction you observe through the eyepiece, making the operation more convenient.
◇ The transmitted light adopts a 12V100W ultra long life halogen light box with a preset center, which does not need to be adjusted after replacing the bulb.
◇ Specialized bright field objective lens converter, 5/6/7 holes optional.
◇ Professional flat field semi apochromatic fluorescent objective lens
The ultra large numerical aperture design provides high-definition and high contrast microscopic images across the entire field of view. When observing fluorescence, the image is bright and clear, with a pure black background and outstanding performance in ultraviolet fluorescence. It is the best choice for professional fluorescence observation of various types of cells and pathological sections.

◇ Shake out achromatic condenser lens (N.A.0.9) with variable aperture stop and aperture number identification, effectively matching the illumination requirements of high and low magnification objective lenses, ensuring sufficient and uniform illumination effects for all magnifications and fields of view

◆ Introduction to Fluorescence:
Multi functional reflective lighting fixture:
Multi purpose RX50 reflective fluorescent illuminating device, capable of using up to 6 fluorescent color filter groups simultaneously. The rotary switching mechanism is convenient and comfortable to use, effectively improving the speed of filter switching. It is particularly convenient for observing multi-color or fluorescence in situ hybridization. The high-precision and high stability turntable mechanism, combined with high-performance imported filters, ensures that there is no drift in the image plane when observing multi-color fluorescence in situ hybridization images.
The front end of the luminaire is equipped with a light gate switch, which can be used for short-term interruption observation to prevent fluorescence quenching caused by prolonged excitation of fluorescent samples.
A light barrier can prevent weak ultraviolet light from affecting the human body.
Equipped with filter slot, aperture stop and field stop lever. Using ND attenuation film or reducing aperture stop/field stop can reduce the excitation light intensity, thereby reducing the attenuation of sample fluorescence.
The objective lens is used for adjusting the center of the mercury lamp filament. After installing or replacing the mercury lamp, it is necessary to adjust the center of the filament to ensure sufficient and uniform fluorescent lighting.
◇ Mercury lamp power control system:
A brand new digital power control system with a usage time counter and current value display, helping users determine the usage status of mercury lamps.
◇ Two types of light boxes are available, providing high-quality lighting for multiple purposes:
The newly developed 100W ultra-high voltage direct current mercury lamp chamber has an improved thermal cycle design, significantly reducing the surface temperature of the lamp chamber and avoiding the risk of burns during use. The center adjustment of the filament is more convenient.
75W xenon lamp source available for selection.
◇ Standard fluorescence filter module parameters. It can meet the needs of the vast majority of routine scientific research, and can also provide specialized modules for fluorescence probe observation according to the special requirements of specialized detection and analysis.
