MAGUS Bio D250T Biological Digital Microscope

The MAGUS Bio 250T 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

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

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.

Illumination

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.

Accessories

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 250T microscope, the devices match the microscope optimally and maximize its capabilities.
