MAGUS Bio 230T is a biological trinocular microscope for laboratory and research observations in the field of medicine pharmaceuticals forensics biotechnology etc. It is suitable for the observation of flat biological translucent and transparent specimens: thin sections and smears. Equipped with achromatic objectives and a halogen bulb the transmitted light microscopy technique (brightfield) is used for studying samples. The design of the microscope provides the possibility of installing additional accessories that allow for the use of other microscopy techniques: darkfield phase contrast polarized light.


The trinocular head has a vertical tube for mounting a digital camera. The camera (not included) is an excellent solution for making digital archives of your studies and output images to an external monitor screen. To adjust the observation tubes to fit the user’s height there is an option to rotate them 360°. The left tube is equipped with a diopter adjustment ring.

The revolving nosepiece is oriented toward the interior which leaves the space above the stage free. Five objectives can be simultaneously mounted into the nosepiece (4 objectives are included in the kit and the 5th slot is left for an additional objective). In the basic configuration the infinity-corrected objectives provide magnification from 40 to 1000x. With optional eyepieces the upper limit can be increased up to 1500 1600 or 2000x.


The halogen bulb produces warm-spectrum lighting that reduces eye strain and is ideal for long hours of working with the microscope. The bulb is 30W and therefore the brightness and contrast of the transmitted image is high regardless of the type of objective or observation technique being used.

The Abbe condenser is height-adjustable and can be centered. The illumination is controlled by adjusting the iris and field diaphragms and there is an option to set up the Köhler illumination for better image clarity. The condenser has a slot for installing a phase or darkfield slider which speeds up the process and makes it easier to switch between different microscopy techniques.

Stage and focusing mechanism

There is no positioning rack on the stage. This is an advantage of the mechanical stage design as it makes it easier to operate the microscope. The specimen can be moved smoothly across the stage. The mechanical attachment is removable (it can be removed for manual scanning).

There is coarse and fine focusing adjustment the focusing knob movement is smooth and easy and it requires no further effort. The coarse focusing mechanism has a lock knob and tension adjustment. The focusing knobs are coaxial positioned for maximum comfort during long hours of observation and are located at the microscope base so that you can comfortably rest your hands on the table.


To maximize the capabilities of the MAGUS Bio 230T microscope you can further upgrade it with some accessories. It may include eyepieces and objectives digital cameras and calibration slides darkfield condensers polarized light and phase contrast microscopy observation devices.
