Magnification: 40–1000x. Trinocular head with adjustable tilt angle, motorized revolving nosepiece and condenser, plan achromatic objectives, 3W LED illuminator, intelligent lighting control system

Research grade microscope. Designed for observing transparent and translucent biological samples, such as smears and cross sections in transmitted light using the brightfield method. Installation of additional accessories will allow for darkfield, phase contrast, differential interference contrast, fluorescence, and polarization methods.
The motorized revolving nosepiece and condenser automate the process of switching objectives and adjusting the lighting system for each one. The user is not distracted by the settings and, therefore, their attention is focused on the research at hand and that accelerates the activity.
The microscope is suitable for microbiological analysis, medical diagnostics, and solving scientific and research problems.

Description

Microscope head
Trinocular head with infinity-corrected optics. The user selects the most comfortable angle of inclination of the microscope head in the range of 0° to 35°. The digital camera is mounted in the trinocular tube. The beam splits 0/100, 100/0, or 80/20.
The base kit includes 10x/25mm eyepieces with diopter adjustment and a long eye relief for working with glasses.

Revolving nosepiece and objectives
A motorized revolving nosepiece for 6 objectives is oriented toward the interior: The user sees 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 objectives are plan achromatic, parfocal height – 60mm.
Above the nosepiece is a slot with a plug for installing an analyzer, compensators, or differential interference contrast sliders.

Remote control of the revolving nosepiece
The front panel of the microscope has objective selection buttons. By pressing a button, the revolving nosepiece automatically sets the selected objective to its working position. A separate button is used to switch between the two most commonly used objectives.
On both sides of the body, next to the focusing knobs, there are buttons for rotating the nosepiece.
The lighting and condenser position are automatically adjusted to match the selected objective.
These features improve user comfort, speed, and efficiency. They provide an advantage for microphotography as the shooting conditions remain the same for each sample.

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 sharply increases when switching from a higher magnification objective to a lower magnification one. A sharp increase in brightness causes eye fatigue. MAGUS Bio 290T is equipped with intelligent brightness control. The microscope remembers the brightness for each objective that the user has selected and automatically sets the brightness when turning the nosepiece. Intelligent control reduces the time required to adjust the brightness. MAGUS Bio 290T increases user comfort and saves time even when the work being carried out requires frequent magnification changes.

Focusing mechanism
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.

Stage
A plate of chemically tempered Gorilla Glass is installed on the stage. The plate is durable, resistant to mechanical and chemical impact, and is easy to keep clean. 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 user’s hand rests on the table without strain.

Condenser
Optimal condenser settings for each objective: The swivel auxiliary lens automatically moves out of the beam path for low-magnification objectives and returns back for objectives with magnifications greater than 10x. One less manual step – for fast and convenient operation. The user can also individually adjust the position of the swivel auxiliary condenser lens for specific studies.
The condenser is height-adjustable and can be centered. Mounting type: dovetail.
The condenser ring adjusts the iris aperture diaphragm. The condenser body has white aperture markings and color markings for the objective magnification, and the ring has an indicator marker. To achieve the contrast on each objective, it is recommended to rotate the ring so that the indicator marker matches the aperture or magnification marking of the objective being used.

Illumination
The transmitted light illuminator has a 3W LED. The color temperature does not change when adjusting the brightness. The LED has a lifespan of 50,000 hours.

Köhler illumination in transmitted light
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 field aperture control is located on the right at the bottom of the body, next to the focus adjustment area. This simplifies the Köhler illumination setup.
The Köhler illumination improves the image quality of the observed sample: Each objective achieves maximum resolution, and 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.

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 290T provides user comfort during work.
Motorized components increase speed and simplify repetitive tasks when changing objectives frequently.
The user chooses a comfortable angle of inclination of the microscope head so that the back and neck do not get tired.
The focusing knobs are located at the bottom of the body. The user does not need to 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.

Accessories
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 that you use most often.
Phase contrast devices, fluorescent attachment, darkfield condensers, polarization devices, and DIC devices extend the contrast methods and allow the study of objects that are invisible in the brightfield.
A digital camera outputs the microscope image to a monitor, store files, and the software takes real-time measurements of specimens.
A calibration slide is used to measure objects and can be combined with the eyepiece with a scale or with the camera software.
