MAGUS Bio D290T LCD Biological Digital Microscope

The research-grade microscope. The microscope is designed for observing transparent and translucent biological specimens, such as smears and sections, in transmitted light using the brightfield technique. Installation of additional accessories will allow for darkfield, phase contrast, differential interference contrast, fluorescence, and polarization techniques.
The motorized revolving nosepiece and condenser automate the process of switching objectives and adjusting the lighting system for each of them. The user is not distracted by the settings and therefore focused on the research, which accelerates the speed of operations.
The microscope is suitable for microbiological analysis, medical diagnostics, scientific and research tasks.
The microscope is equipped with an 8MP camera and three video interfaces: HDMI, USB 3.0, and Wi-Fi. It can be connected simultaneously to several devices: monitor, laptop, and desktop computer. The software complements the system with analysis and documentation functions.
The monitor in a digital microscope has 4K resolution.

Digital camera

MAGUS CHD40 is a digital HDMI camera with three video interfaces and automatic switching between 4K and Full HD depending on the monitor resolution.
The camera is equipped with an 8MP sensor and it produces a realistic image in 4K resolution (3840x2160 pixels) when connected via HDMI or USB 3.0. When connected via Wi-Fi, the image resolution is Full HD (1920x1080 pixels).
The camera uses an HDMI interface to connect directly to a TV, monitor, or projector. In this mode, the camera operates autonomously without a PC. The HDMI interface provides a high and stable transfer rate from the camera to the external screen. The connection to a computer is made via Wi-Fi or USB 3.0. Video is recorded at 30fps.
The camera combines high FPS and high bandwidth HDMI and, therefore, videos are vivid with no freezes or gaps between frames. At maximum resolution, the image is well-detailed, moving objects are visible without any bugs, and object movement is displayed without delays.

Monitor

The MAGUS MCD40 Monitor is designed to use a visualization system of the MAGUS microscope.
It connects to a microscope-mounted camera to display a real-time image. It is compatible with MAGUS HDMI cameras operating in 4К resolution.
The screen diagonal is 13.3 inches. The IPS sensor delivers a bright image with large viewing angles: If you look at the monitor at an angle, there is no color distortion.
The display can be placed on a folding stand on a table or mounted directly on the camera, whichever is more convenient for the user.

Microscope head

Trinocular, 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 basic configuration includes 10x/25mm eyepieces with diopter adjustment and eye relief to work 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 distance – 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. When you press a button, the revolving nosepiece automatically sets the selected objective to its operating 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.

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. Switching from a higher to a lower magnification objective causes eye fatigue, as the image brightness in the eyepieces increases sharply. The MAGUS Bio D290T LCD, which is equipped with intelligent brightness control, solves this problem. The microscope remembers the brightness for each objective that the user has selected and automatically sets this brightness when turning the nosepiece. Intelligent control reduces the time required to adjust brightness. MAGUS Bio D290T LCD increases user comfort and saves time even when the given work requires frequent magnification changes.

Focusing mechanism

The microscope features low-position coaxial coarse and fine focusing knobs. 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 object 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

The stage plate is made of sapphire glass. The hardness, durability as well as scratch and chemical resistance of the sapphire glass is second only to diamond glass. It significantly outperforms the popular chemically tempered Gorilla Glass. According to the Mohs scale (a ten-point scale of relative hardness of mineral surfaces), Gorilla Glass scores 6.8, sapphire scores 9, and diamond has a score of 10.
The specimen holder is secured with two screws and can be easily removed during manual scanning.
The height-adjustable stage control knob ensures user comfort, allowing the hand to rest on the desk for fatigue-free operation. The control knob also features tension adjustment, which allows you to select the optimal rotation tension for smooth and precise specimen movement.

Condenser

Optimal condenser settings for each objective: The flip-down 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 flip-down 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.

Light source

The transmitted light illuminator uses a 3W LED. The color temperature does not change when you adjust the brightness. The LED lifetime is 50,000 hours.

Köhler illumination in transmitted light

The light source is located at the rear of the microscope, and the light is directed to the collector using a mirror.
The image contrast is controlled by the condenser aperture diaphragm, while the illuminated field area is adjusted by the field diaphragm. 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 D290T LCD provides user comfort during work.
Motorized components increase speed and simplify repetitive tasks when changing objectives frequently.
The adjustable head allows the user to select a comfortable viewing angle, reducing neck and back strain.
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 specifically for this microscope.
Optional objectives provide additional magnification.
Eyepieces extend the magnification range of the microscope. Optional eyepieces help you maximize the potential of the objective that you use most often.
Optional attachments for phase contrast, epi-fluorescence, darkfield, polarization, and DIC expand the range of microscopy techniques, allowing you to study specimens invisible in brightfield.
Digital cameras output 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 can be combined with the eyepiece with a scale or with the camera software.
