Research grade microscope. Designed for observing transparent and translucent biological samples, such as smears and cross sections in transmitted light using the brightfield method. The installation of additional accessories will allow for darkfield, phase-contrast, fluorescence, and polarization methods.
The coded revolving nosepiece maintains a comfortable brightness level when switching objectives. Intelligent control of microscope lighting increases the comfort and speed of the researcher’s work. Thanks to the “smart” functions, there is no need to bother with the settings; the user’s attention is completely focused on solving their tasks.

Microscope head

Trinocular head with infinity-corrected optics. Eyepiece tubes rotate 360°. The user can adjust the eye relief on the eyepiece to fit their height. The digital camera is mounted in the trinocular tube. The beam splitting is 50/50.
The base kit includes 10x/22mm eyepieces with diopter adjustment and a long eye relief for working with glasses.

Revolving nosepiece and objectives

The coded revolver for 5 objectives is oriented toward the interior: The user can see the objective inserted into the optical path, and the space above the stage is free. An additional objective can also be installed in the free slot in order to achieve extra magnification. The parfocal distance is 60mm.
Above the revolver, there is a slot with a plug for installing the analyzer.

Maintaining comfortable brightness levels when switching magnifications

The objectives of different magnifications transmit light with different levels of intensity, and so each time you change objectives, the brightness of the light must be adjusted. In addition, brightness increases sharply when switching from a higher magnification objective to a lower magnification one. A sharp increase in brightness causes eye fatigue. MAGUS Bio 270T is equipped with intelligent brightness control. The optimal level of light brightness is automatically switched for each objective, thereby eliminating unexpected changes in brightness when changing magnification. This feature optimizes your workflow and reduces eye fatigue.

Focusing mechanism

With a large number of study objects, the operator constantly uses the fine focusing knob for their work. To reduce wrist strain, the microscope uses a responsive mechanism with smooth travel. The fine focusing knob has special grooves for your fingers. Fine-tuning the focus is effortless, and the right hand does not get tired.
The coarse and fine focusing knobs are coaxial and located low. The researcher can place their hands on the table and take a comfortable position in front of the microscope.
The coarse focus lock knob helps you quickly adjust the microscope after changing the subject of study. The knob is located on the left side of the microscope on the same axis as the focusing mechanism.
The ring on the right side adjusts the tension of the coarse focusing travel. The user adjusts the comfortable tension for work.


To ensure the ergonomic operation of the stage, it does not have an X-axis positioning rack. The belt-driven mechanism allows for the smooth movement of the specimen. The specimen holder is secured with two screws and can be easily removed during manual scanning.
The long stage control handle ensures user comfort while working: The hand rests on the table without strain.


The Abbe condenser is height-adjustable and can be centered. Mounting type: dovetail.
The condenser ring adjusts the iris aperture diaphragm. The condenser body has an aperture marking, and the ring has an indicator marker. To achieve the contrast on each objective, it is recommended to rotate the ring so that the index marker matches the aperture marking of the objective being used.


The transmitted light illuminator contains a 3W LED. The microscope illuminator has the function of adjusting the color temperature in the range from 3000 to 7000K. The user selects a color temperature that is comfortable for the eyes and easily changes it with one button when, for example, examining an object requires a change in light.
The LED has a lifespan of 50,000 hours.

Köhler illumination in transmitted light

The light source is located in the base at the back of the microscope, and the light is directed to the collector using a mirror. The image contrast is regulated by the aperture diaphragm of the condenser, and the illuminated field area is regulated by the field diaphragm of the collector.
The Köhler illumination improves the image quality of the observed sample: Each objective achieves maximum resolution, the field of view is illuminated evenly without darkening at the edges. The object of study is in sharp focus, and the image artifacts are removed.

LCD status screen

The LCD screen on the base of the microscope displays the objective magnification, brightness, and color temperature of the light source as well as operating mode (“sleep”, “eco”).
Using the screen and two knobs, the microscope user adjusts the brightness, selects the color temperature, locks brightness adjustment, and sets the sleep mode and the auto-off timer.

Ergonomic design

Physical discomfort causes fatigue and reduces productivity. The ergonomic design of the microscope plays an important role in everyday scientific research. MAGUS Bio 270T provides user comfort during work.
By rotating the microscope head, the user selects a point of view height so as not to strain their back and neck.
Focusing knobs are located at the bottom of the body. The user does not strain their hands. Thanks to the smooth movement of the mechanism, the user can effortlessly focus on the object.
The microscope is operated with minimal hand movement since the long stage control handle and fine focusing knob are located in the same working area.
The microscope is equipped with a special carrying handle.
The design for the hidden placement of the power adapter and power cord improves the workplace esthetic and safety of carrying the microscope as well as simplifies storage of the device.


There is a line of accessories designed for this microscope.
Optional objectives provide additional magnification.
The eyepieces extend the magnification range of the microscope. Optional eyepieces help you maximize the potential of the objective you use most often.
The phase contrast device, reflected light illuminator, dark field condensers, and polarization device extend contrast techniques and allow the examination of objects invisible in brightfield.
A digital camera outputs the microscope image to a monitor, store files, and software takes real-time measurements of specimens.
A calibration slide is used to measure objects, and it can be combined with the eyepiece with a scale or with the camera software.
