MAGUS Bio VD300 LCD Biological Inverted Digital Microscope
With a camera and monitor. Magnification: 100–400x. Trinocular head, infinity plan achromatic objectives, 9W LED illuminator, condenser with a phase slider slot

This microscope is designed for studying liquid precipitates, cell colonies, living cells, tissue cultures, and other stained and unstained specimens in laboratory glassware. Its inverted design allows for the use of Petri dishes, multi-well plates, vials, roller bottles, and flasks up to 70mm with a bottom thickness of 1.2mm. The microscope uses special objectives for working with such glassware. The transmitted light microscopy technique (brightfield and phase contrast) is used for studying samples. Areas of application: education, laboratory work and research in medicine, biotechnology, biology, virology, agriculture, ecology, toxicology, pharmacology, etc.

Digital camera
The MAGUS CHD30 digital camera is equipped with a 2MP sensor and produces realistic Full HD images at a resolution of 1920x1080px. The camera features high light sensitivity, auto focus function, and it is suitable for fluorescent observations.
The camera uses an HDMI interface to connect directly to a TV, monitor, or projector. In this mode, the camera operates autonomously without a connection to a PC. The HDMI interface provides a high and stable transfer rate from the camera to the external screen. You can connect it to a PC via Wi-Fi.
Video is recorded at 60fps or 25fps depending on the video output interface.
The camera combines high FPS and high bandwidth HDMI. Therefore, videos are vivid with no freezes or gaps between frames. At maximum resolution, the image is well-detailed, moving objects are visible without bugs, and object movement is displayed without delays.

The MAGUS MCD20 Monitor is designed to use a visualization system of the MAGUS microscope.
It is connected to a camera mounted on the microscope to display real-time images. It supports MAGUS full HD resolution HDMI cameras.
The screen diagonal is 13.3 inches. The IPS matrix provides bright images with large viewing angles. If you look at the display at an angle, the color reproduction is not distorted.
The display can be placed on a folding stand on a table or shelf or mounted directly to the camera or microscope stand.

Microscope head
A trinocular head with infinity plan achromatic objectives. The digital camera is mounted in the trinocular tube. 50:50 beam splitting.

Revolving nosepiece
A 4-objective revolving nosepiece that is mounted on a stand under the stage.

Infinity plan achromatic objectives with a long working distance for dishes with a bottom thickness of 1.2mm. The four objectives are for the brightfield microscopy technique and one objective – for the phase contrast technique.

Focusing mechanism
The coaxial coarse and fine focusing knobs are located at the base of the microscope on both sides. The user can place their hands on the table and take a relaxed pose while observing. The focus adjustment is smooth and effortless. On the right side, there is a coarse focusing lock knob for quick setting adjustments after changing the sample. On the left side, there is a coarse tension adjustment ring for further adjustment.

There is a fixed stage with a mechanical attachment for moving the laboratory glassware in two mutually perpendicular directions. The smooth and subtle movement of the object augments the accuracy of the study: No part of the specimen will be overlooked. The travel knob is located at the bottom, and so the user will not strain their right wrist. The microscope set includes three dish holders for glassware of different sizes.

A phase contrast slider is installed in the condenser. The phase contrast rings can be centered. The installation of such a slider saves time when switching between microscopy techniques.

Light source
The 9W LED provides bright illumination, which is sufficient for observations in brightfield and phase contrast with all kinds of objectives. The color temperature does not change when you adjust the brightness. The LED has a lifespan of 50,000 hours.

There is a line of accessories designed specifically for this microscope. There are additional 20x and 40x phase objectives for studying 0.7µm and 0.4µm non-contrast objects. Eyepieces extend the magnification range of the microscope. Additional eyepieces will help you use the full potential of an objective that is used more often. A digital camera that outputs the microscope image to a monitor and stores files, and the software that takes real-time measurements of specimens. A calibration slide for measuring objects that can be combined with an eyepiece with a scale or the camera software.
