MAGUS Bio VD350 LCD is a biological inverted microscope, which is used for studying stained and unstained samples in laboratory ware – Petri dishes, flasks, plates. The height of the dishes can be 55mm, and if you tilt the illuminator stand – up to 165mm. The bottom thickness of compatible ware is up to 1.2mm. The microscope, which utilizes the brightfield field and phase contrast microscopy techniques in the transmitted light, has a trinocular tube/side port camera for mounting a digital camera and monitor. It is used for routine laboratory and research work as well as teaching.

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.


MAGUS MCD monitors work in combination with MAGUS CHD cameras to form a complete imaging system for MAGUS microscopes.
The connection to the camera occurs via its HDMI interface. The monitor displays real-time images. Its IPS LCD display has a wide viewing angle, high brightness, and good contrast. When looking at the screen even from a large angle, the image is not distorted. The screen size is 13.3''.
The monitor can be installed on a horizontal surface using a folding stand or mounted directly on a camera or tripod.


When assembling the microscope, you can select the position of the trinocular head: It can be rotated 180° to adjust the height of the exit pupil. Use the vertical tube to mount the monitor and the side port on the microscope body to mount a digital camera. The beam splitting on the body is 100/0 or 0/100 as well as 50/50 on the trinocular tube (when it is open) or 100/0 (when it is closed).

Four infinity plan achromatic objectives are included, one of which is a phase objective. Once four of them are installed in the revolving nosepiece, one slot is left free for an additional objective.


The phase-contrast condenser enables easy and convenient switching between microscopy techniques. It has four working positions: a free aperture for the brightfield technique as well as 10x, 20x, and 40x apertures for phase contrast using a suitable magnification objective.

The transmitted light source is a 30W halogen bulb that emits light of the color temperature that allows for comfortable work. It is brightness adjustable and is AC powered. The illumination system offers the use of the Köhler illumination to enhance image quality.

Stage and focusing mechanism

Four dish holders for the stage are included. They can be moved along the X and Y axes using a mechanical attachment, while the stage itself remains stationary. The holders are designed to hold labware of various sizes.

The focusing mechanism runs smoothly. The coarse focusing mechanism has a lock knob and tension adjustment. Fine focusing scale value: 2μm. The knobs are located at the base of the microscope so you can keep your hands in a more relaxed position while working.


There are additional eyepieces, phase objectives, digital cameras, and calibration slides for the microscope to maximize the capabilities of the microscope.
