The MAGUS Bio 230B microscope is designed for laboratory and scientific research in order to observe biological specimens such as thin sections or smears. The transmitted light microscopy technique (brightfield) is used for sample analysis. If necessary the microscope can be equipped with additional accessories for darkfield polarized light and phase contrast techniques. The microscope can be applied in such areas of research as pharmaceutical industry medicine biotechnology environmental protection forensics and agriculture.


The microscope has a binocular head. The observation tubes can be rotated 360° thereby allowing the user to adjust the position to fit their height. There is a diopter adjustment ring on the left tube. The revolving nosepiece has 5 slots and it is oriented toward the interior – the user can see the objectives inserted into the optical path and therefore the space above the stage is free. Four achromatic objectives are included in the kit and the fifth slot can be used to mount an optional objective.

The optics are infinity corrected. The basic microscope magnification ranges from 40 to 1000x. With additional eyepieces it can be extended up to 1500 1600 and 2000x. If necessary a digital camera (not included) can be mounted into the eyepiece tube.


The light source is a halogen bulb located at the microscope base. The warm lighting reduces eye strain and is ideal for long hours of working with the microscope. The 30W halogen lamp enables bright and high-contrast images to be produced with any type of objective and any microscopy technique (including darkfield and phase contrast).

The Abbe condenser can be centered and its position is height-adjustable. A phase contrast or darkfield slider can be installed in a special slot thereby allowing you to easily switch between microscopy techniques. The field diaphragm makes it possible to set up the Köhler illumination.

Stage and focusing mechanism

The stage does not have a positioning rack which makes it easier to work with the microscope. A mechanical attachment which can be removed if necessary ensures the smooth movement of the specimen across the stage.

The coarse and fine focusing knobs are coaxial (on the same axis) and located on both sides at the lower part of the microscope. Such positioning of the focusing knobs enables you to rest your hands freely on the table and sit comfortably for long periods of work. The focusing adjustment is smooth and requires no further effort. The coarse focusing has a lock knob and focus tension adjustment.


Additional equipment such as objectives eyepieces phase contrast devices darkfield condensers polarizing devices digital cameras or other accessories will expand the capabilities of the microscope. They are designed for MAGUS Bio 230B and available on request.
