Biological microscope MAGUS Bio 230B
The MAGUS Bio 230B microscope is designed for use in technical and research laboratories to observe biological samples such as thin cross-sections or smears. Samples are analyzed using transmitted-light microscopy (brightfield). If necessary, the microscope can be equipped with additional accessories for darkfield, polarized-light, and phase-contrast observations. This microscope is suitable for use in fields such as the pharmaceutical industry, medical research, biotechnology, environmental protection, forensic science, and agriculture.

The MAGUS Bio 230B microscope is designed for use in technical and research laboratories to observe biological samples such as thin cross-sections or smears. Samples are analyzed using transmitted-light microscopy (brightfield). If necessary, the microscope can be equipped with additional accessories for darkfield, polarized-light, and phase-contrast observations. This microscope is suitable for use in fields such as the pharmaceutical industry, medical research, biotechnology, environmental protection, forensic science, and agriculture.
Optics
The microscope is equipped with a binocular head. The optical tubes can rotate by 360°, allowing users to adjust their position according to their height. A diopter adjustment ring is located on the left tube. The revolving nosepiece has 5 slots and is oriented inward: this allows users to see which objective is in the optical path while keeping the space above the stage clear. Four achromatic objectives are included, and the fifth slot can be used to hold an additional objective.
The optics are infinity-corrected. The microscope's basic magnification ranges from 40x to 1000x. With additional eyepieces, it can be extended to 1500x, 1600x, and 2000x. If necessary, a digital camera (not included) can be mounted in the optical tube.
Illumination
The light source is a halogen lamp located in the microscope base. Its warm light reduces eye strain and is ideal for long hours of microscope use. The 30 W halogen lamp produces bright, high-contrast images with any type of objective and microscopy technique (including darkfield and phase contrast).
The Abbe condenser can be centered and its height adjusted. A darkfield or phase-contrast slider can be inserted into a dedicated slot, making it easy to switch between observation techniques. The field diaphragm enables Köhler illumination.
Stage and focusing mechanism
The stage has no positioning rack, making the microscope easier to use. A mechanical insert, which can be removed if necessary, ensures smooth movement of the sample on the stage.
The coarse and fine focus knobs (macro- and micrometer screws) are coaxial and located on both sides of the microscope, near the bottom. The position of the focus knobs lets users rest their hands comfortably on the table and sit comfortably during prolonged observations. Focusing is smooth and requires no effort. The coarse focus has a locking knob, and the tension of the coarse focus screw can be adjusted.
Accessories
Additional equipment, such as objectives, eyepieces, phase-contrast devices, darkfield condensers, polarization devices, digital cameras, or other accessories, can expand the capabilities of the microscope. They are designed for the MAGUS Bio 230B and are available on request.
