Description

Digital camera
MAGUS CBF90 is a science camera with 5MP resolution and a 2/3" sensor for the brightfield microscopy technique.
The camera produces a realistic image in 2448x2048px. When observing with low and medium magnification objectives, the camera will show more fine details.
Video is recorded at 35fps or 50fps depending on its resolution. Videos are smooth, with soft and subtle transitions between frames. The movement of the sample is displayed in real time with no delays. The camera provides convenient work with moving objects and is suitable for conducting demonstrations in a classroom.
The camera is equipped with a USB 3.0 interface. The data transfer rate is 10 times faster than that of USB 2.0 cameras. The high-speed camera is recommended for professional laboratories, research, or university training.
 
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 on the vertical 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 with a parfocal distance of 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, 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 increases user comfort and saves time even when 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 user’s 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 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.
 
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 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 for 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 that are invisible in brightfield.
A calibration slide is used to measure objects and can be combined with the eyepiece with a scale or with the camera software.
