Features of RBMC-A:
1. Plan achromatic objective lens: Utilizes standard professional full-coating technology, providing clear and sharp images with chromatic aberration correction.
2. Large-sized mechanical stage: Double-layer mechanical structure, facilitating sample movement and location during experiments, capable of holding two samples at once.
3. Wide-angle high-definition plan eyepiece: Equipped with a 10×/18mm wide-angle visual observation, offering uniform and bright field of view with ±5 diopter adjustment, ensuring clear observation even for those wearing glasses.
4. 360° rotatable observation head: The observation head can be adjusted and rotated 360°. Interpupillary distance is adjustable from 55 to 75mm.

Features of RBMC-B:
1. High eye point wide-angle eyepiece: Hinged binocular observation tube, providing a large and clear field of view. The diopter adjustment ring on the eyepiece tube can be adjusted for better imaging and more comfortable observation.
2. Plan/phase contrast objective lens: The optical system significantly enhances imaging resolution and clarity.
3. Condenser system, providing sharp and clear imaging.
4. Capable of microscopic observation within culture flasks or dishes.

Features of RBMC-C:
1. Utilizes ultraviolet light as the light source, suitable for observing certain substances in cells.
2. Multi-layer image fusion technology.
3. Four adjustable wavelengths: Equipped with a 5W high-brightness monochromatic LED, featuring a modular design.
4. Precise image measurement.
5. Double-layer moving stage: XY-axis double-layer mechanical moving stage, operable with one hand.
6. Transmitted illumination system: LED fluorescent light source, using high-brightness, high-quality narrow-band LEDs with a lifespan of over 50,000 hours.

Precautions：
1. Check the instrument: Ensure that all parts of the microscope are intact and undamaged, and the optical lenses are clean.
2. Place it steadily: Put the microscope on a stable laboratory bench to avoid vibration.
3. Operate gently: When adjusting the focus and switching objectives, do so gently to avoid excessive force.
4. Protect the lenses: Use lens paper or a soft cloth to clean the lenses, and avoid touching them directly with your hands.
5. Use oil immersion objectives correctly: When using oil immersion objectives, add an appropriate amount of cedarwood oil, and clean the lenses promptly after use.
6. Adjust the light source: Adjust the light source brightness as needed to avoid overly strong light affecting observation.
7. Clean the instrument: After use, clean the stage and lenses, and cover it with a dust cover.
8. Store properly: Return the microscope to its original position, turn the objectives to the slots, and avoid long-term exposure to dust.
9. Regular maintenance: Regularly check the mechanical and optical components of the microscope, clean the dust in time, and ensure the performance of the instrument.
