The MAGUS Bio 260T microscope is a daily microscope that can be used for laboratory and scientific research or for educational purposes. The microscope works with thin transparent and translucent specimens using the brightfield method. However, additional components can be installed on the device to expand its capabilities to use darkfield, phase contrast, polarized, and fluorescent light methods.
The model is equipped with a coded revolving nosepiece that can accommodate up to five objectives. “Smart” lighting automatically switches with the turn of the revolver and is adapted to the parameters of each objective. Thanks to this feature, there is no need to waste time adjusting the light, which is particularly important in the educational process or when you need to frequently change the magnification.

The microscope has a trinocular head that adopts the infinite optical system. The height of the pupil is adjustable. Its position is adjusted by rotating the tubes up to 360°. A digital camera is installed in a trinocular tube. The light is distributed to the camera and eyepieces in a 50/50 ratio. The microscope kit includes basic 10x/22mm eyepieces with a diopter adjustment mechanism. No adjustment is made on the tubes. Users who wear glasses can benefit from the included rubber eyecups that protect the glass from abrasions and scratches.

The revolving nosepiece for 5 objectives is equipped with an automatic lighting control system. When changing the magnification, the user observes strong fluctuations in the light level in the eyepiece: Objectives of different magnifications transmit light in different ways. Intelligent lighting allows you to set the light level for a specific objective once, and then when you turn the nosepiece, the light will switch automatically. The microscope kit includes 4 objectives; the user can place an objective in the fifth slot as needed. The parfocal distance is 60mm. The slot above the revolving nosepiece is used to mount the analyzer; while the analyzer is not installed, the slot is closed with a plug.

The specimen stage is designed with a belt drive: The specimen moves softly and smoothly. There is no X axis positioning rack, and so working with the microscope is more ergonomic and comfortable. The specimen holder is fixed with two screws and can be removed when necessary. Another convenient detail is the long stage control handle. The user can use the microscope with their hands resting on the table without straining their arms and body.

The condenser can be adjusted to the desired position both vertically and relative to the optical axis (held on a dovetail mount). The iris diaphragm is adjusted by a ring: It has a marker, and objective magnification indicators are shown on the condenser body. For a contrast image, the marker is set in accordance with the installed working objective. The condenser can be supplemented with darkfield or phase contrast sliders: There is a special slot for it.

The microscope is focused using coaxially located coarse and fine adjustment knobs. Coarse focusing is done using the knob on the left side. There are fine focusing knobs on both sides of the stand, and the right one has special, convenient grooves for your fingers. Additional convenience is provided by the travel adjustment ring that allows you to adjust the tension of the coarse focusing travel in a way that is convenient for you. All of the knobs and the ring are located at the bottom of the stand: the user controls them by resting their hands comfortably on the table.

Lighting in the microscope is produced by a 3W LED mounted in a transmitted light illuminator. The lighting temperature remains stable even with changes in brightness. The optional research methods on this microscope involve the use of Köhler illumination. Thanks to it, the entire field of the specimen is illuminated uniformly, and artifacts such as dust or the image of the light source will not be visible through the eyepiece or digital camera.

You can view the selected operating parameters and adjust them using the built-in display. It is located at the base of the microscope. The display shows the magnification of the working objective, lighting parameters, operating mode, and automatic shutdown time.

Additional elements can expand the functionality of the device. A set of eyepieces can increase the magnification spectrum. For additional methods of working with specimens that cannot be seen in the brightfield method, it is necessary to supplement the microscope with a phase contrast device, a darkfield slider, or a polarization device. A digital camera can help capture the results of the study in a photo or video or display the image on the screen. You can measure objects using a calibration slide in conjunction with an eyepiece with a scale or a digital camera.
