A biological microscope is a precision optical instrument used to observe biological slices, cells, and bacteria, as well as live tissue cultures, liquid residues, and other transparent or semi-transparent objects, including powders, small particles, and more.

Biological microscopes are employed in medical and healthcare institutions, higher education, and research institutes for the observation of microorganisms, cells, bacteria, tissue cultures, suspensions, precipitates, etc. They allow continuous observation of cell and bacterial reproduction processes in culture fluids. Widely used in fields like cytology, parasitology, oncology, immunology, genetic engineering, industrial microbiology, botany, and others. The optical technical parameters include numerical aperture, resolution, magnification, depth of focus, field of view width, coverslip thickness, working distance, etc. These parameters are not necessarily higher is better, as they are interconnected and mutually constrained. In practical applications, the relationships between these parameters should be coordinated based on the purpose of microscopy and the actual situation while ensuring resolution.

The N-800M is a widely applicable research microscope that meets the microscopic observation needs of most researchers. It provides realistic, flat, and bright imaging, is easy to operate, and has a certain level of expandability.

N-800M laboratory biological microscope
  • Infinite optical system with standard Kohler illumination for superior optical quality and improved image quality.
  • Low-position, front-position coarse and fine focusing axis; one-handed operation of coarse and fine focusing wheels, improving efficiency; combined with a highly stable body structure, providing users with a more comfortable experience.
  • The N-800M laboratory biological microscope, with innovative optical and mechanical design concepts, superior optical quality, and a convenient operating system, provides a comfortable experience for laboratory work.

The infinite optical system, FN22mm field of view observation head, flat field achromatic objectives, even semi-apochromatic objectives, and Kohler illumination provides an excellent optical foundation for imaging. The five-hole objective converter, large-size dual-layer movable stage, and various application accessories expand the scope of this microscope. The ergonomic observation head, low-position focusing mechanism, and platform movement handle reduce user fatigue significantly. In summary, whether used as an advanced teaching microscope or an experimental microscope, it performs exceptionally well.
