MAGUS Bio 230BL is a binocular microscope with achromatic objectives and LED illumination for observing biological samples such as smears and thin sections. The observations are made with the transmitted light microscopy technique (brightfield). The microscope can be equipped with optional darkfield polarized light and phase contrast devices. Areas of application: pharmaceuticals medicine biotechnology veterinary medicine forensics agriculture etc.


The observational tubes rotate 360° which allows you to adjust the eyepieces to fit the height of the observer. There is a diopter adjustment ring on the left tube. A digital camera (purchased separately) can be mounted into the same tube.

Since the revolving nosepiece has 5 slots another objective can be attached in addition to the supplied objectives in order to achieve higher magnification over the possible magnification range. The basic microscope magnification ranges from 40 to 1000x the upper limit may be increased up to 1500 1600 or 2000x by adding additional eyepieces. The optics of the microscope are infinity-corrected. The revolving nosepiece is oriented toward the interior.


The transmitted light source is a 3W LED powered by AC power supply. By adjusting the illumination brightness the color temperature remains the same and the LED has a lifespan of 50 000 hours.

The illumination is controlled by adjusting the aperture and field diaphragms i.e. there is an option to set up the Köhler illumination. The Abbe condenser is height-adjustable and can be centered. There is an option to insert a dark field slider or phase contrast slider into a slot in the condenser. The sliders make it easier for the user to switch from one microscopy technique to another.

Stage and focusing mechanism

You can move the object of study across the stage with the mechanical attachment which can be removed if necessary. The stage does not have a positioning rack and so the mechanical part occupies less space.

Focusing is controlled by moving coarse and fine focusing knobs. These knobs are on the same axis (coaxial) on each side of the microscope. Located at the base they are convenient to rotate with your hands without any effort. The coarse focusing has a lock knob and tension adjustment. The rotation of the knob is smooth and easy.
