The MAGUS Bio D250T biological microscope is a professional instrument for observing biological specimens in transmitted light. The primary observation technique is a brightfield technique (ready-to-use). Darkfield polarization and phase contrast techniques are also available but they require additional microscope accessories. The microscope is excellent for laboratory and research observations in medicine pharmaceuticals forensics agriculture and other fields.

Digital camera

The MAGUS CDF50 digital camera is designed for the brightfield microscopy technique. It offers a low noise level and high light sensitivity. The camera is equipped with a 2.1MP sensor and delivers realistic Full HD images (1920x1080px) when observing with 40x 60x and 100x objectives.
Video is recorded at 96fps at maximum resolution: It is smooth with soft and subtle transitions between frames. The movement of the sample is displayed in real time with no delays. The camera makes it easy to work with moving objects and is suitable for classroom demonstrations. The camera is equipped with a USB3.0 interface. The data transfer speed is 10 times faster than USB2.0 cameras. The high-speed camera is recommended for professional laboratories research or university training.


Plan achromatic objectives provide a clear contrasty and well-detailed image with minimal distortion. The magnification with included objectives and eyepieces ranges from 40 to 1000x and the upper limit can be increased with additional eyepieces. The optics are infinity corrected which means that additional accessories can be installed in the optical path.

The trinocular head has a separate vertical tube for mounting a digital camera (not included). It is positioned vertically. The trinocular head is equipped with 360° rotating tubes and it is possible to adjust the diopter on the left tube. The design of the trinocular head allows you to easily adjust the eye relief to fit the height of the observer.

The revolving nosepiece with objectives is oriented toward the interior and 5 objectives can be inserted into the revolver simultaneously – 4 objectives come with a kit one slot is free. An additional objective will provide extra magnification within the magnification range.


A 30W halogen bulb provides bright illumination allowing for good visibility of sample structures with any observation technique and any objective being used. The lighting is warm which is more comfortable for the eyes during long hours of work. There is a brightness adjustment option. The lighting is powered by an AC power supply.

It is possible to set up the Köhler illumination thanks to a centered and height-adjustable Abbe condenser aperture diaphragm and field diaphragm. There is a slot in the condenser where a darkfield or phase contrast slider can be installed. The slider allows you to quickly switch between research techniques and that which improves performance.

Stage and focusing mechanism

The stage does not have a positioning rack which improves the ergonomics. The mechanical attachment moves the object smoothly and can be removed for manual scanning.

The focusing knobs are located on both sides of the microscope body and closer to the base of the microscope which allows you to put your hands on the table instead of holding them in the air when working for long periods of time. The knobs are coaxial i.e. they are located on the same axis. The coarse focusing mechanism has a lock knob and tension adjustment. The focusing mechanism is smooth and so you do not have to exert any effort when adjusting it.


The line of optional accessories includes eyepieces objectives polarization devices darkfield condensers phase contrast devices calibration slides and digital cameras. Designed specifically for the MAGUS Bio D250T microscope the devices match the microscope optimally and maximize its capabilities.
