MAGUS Bio D250TL Biological Digital Microscope

The MAGUS Bio D250TL microscope studies thin sections and smears of biological samples. Observations are made using the brightfield microscopy technique in transmitted light. A 3-watt LED serves as the light source, and the optics feature infinity plan achromatic objectives. The microscope supports additional accessories, including darkfield, polarization, and phase contrast devices. This microscope is the ideal choice for laboratory analysis, research, and teaching.

Digital camera

Full color camera with SONY Exmor 2.1MP digital CMOS sensor. The sensor is manufactured using back-illumination technology to reduce light scattering and increase the matrix sensitivity (8935mV at 1/30s). The camera produces bright and clear images even in low light. Designed to work in darkfield and brightfield using objectives with a magnification of 40x, 60x, and 100x.

The camera can be mounted on a microscope in two ways: into the trinocular tube via a C-mount adapter or in place of the eyepiece in the tube using an adapter and adapter rings. It is recommended to use an adapter with a magnification from 0.6x to 0.9x with the camera, which will give the widest possible field of view without distortion. After installation, the camera connects to a computer via a USB3.0 port with a data transfer speed of 5Gbps.

Optics

The trinocular head includes two eyepiece tubes for observations and a vertical tube for mounting digital camera (not included). The tubes are 30° inclined for comfortable long working hours and can be rotated 360° to fit the height of the observer. There is a diopter adjustment ring that is located on the left tube.

Objectives are mounted in a 5-slot revolving nosepiece – four objectives are included, one slot for an additional objective is left free. Any optional objective can be installed in the free slot, allowing for additional magnification within the magnification range. The user can see the objective inserted into the optical path during the observation as the revolving nosepiece is oriented toward the interior. It keeps the space above the stage free.

The magnification range is from 40x to 1000x (only applies to the basic configuration). If you add additional objectives, the upper magnification limit will be increased.

Illumination

LEDs mounted at the bottom of the microscope provide bright and even illumination of the object. The color temperature remains the same when changing brightness. The power of the illumination is 3W. It has an operating life of 50,000 hours. The lighting system is powered by an AC power supply.

By adjusting the position of the Abbe condenser and opening or closing the aperture and field diaphragms, it is possible to set up the Köhler illumination. You can use sliders for darkfield and phase contrast techniques (a special slot is provided in the condenser). With the slider, switching between the research techniques is very fast.

Stage and focusing mechanism

The stage has no positioning rack. Therefore, it will not disturb you during observations, and the microscope itself will take up less space on the desktop. The mechanical attachment that moves the sample is removable (useful for manual scanning).

Coarse and fine focusing are used for focus adjustment. The knobs are located on both sides. As they are located closer to the base, you do not have to hold your hands in the air while working. You can relax them on the table. The coarse focusing has a lock knob and tension adjustment. The focus adjustment is smooth and effortless.
