Biological Microscope ML51-N
Research biological microscope ML51-N

ML51-N is a scientific research level biologicla microscope equivalent to Olympus BX43. The microscope is consist of original Olympus BX43 body, equipment with high quality plan achromatic fluorescence objectives and trinocular head offer 25mm wide of view. It is flexible upgrade to fluorescence, phase contrast, dark field, metallurgical and polarization. View is clear, sharp and color reproduction is real, it is popular to professional microscope users has requirement of high quality imaging, widely used for clinical, diagnose, biological study, scientific research and related lines.


  • LIM function:The light intensity manager sets brightness settings according to the specific objective.

  • Light action and low torque stage reduced operator force to move the specimen.

  • Warm light LED light source for transmitted lighting, comfortable for eyes, safety for lab working.

  • Flexible expand to fluorescence, dark field, phase contrast, metallurgical and polarizing functions.

Semi-Apochromat FLN objective

Adopt multi-layer coating technology, specially designed for high resolution and high contrast imaging, the fluorescence performance of high sensitivity ensures the sharpness, clarity and color reduction of the collected image.

Light intensity management

The light intensity management sets the light intensity matching with different objectives. From low to high times it keeps the same brightness of field of vision. No need to adjust the light intensity manually and repeatedly.

Low torque stage

The low fixed stage and objective focusing device improves operation comfort, tiny hand movements can easily adjust the position of the specimen and reduce operation fatigue.
