MAGUS Bio VD350 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 CDF30 digital camera is designed for the brightfield and darkfield microscopy technique. It offers a low noise level and high light sensitivity. The camera is equipped with an 8.3MP sensor and delivers realistic images in 4K resolution (3840x2160pix) with the clearly visible fine details of samples and their structures. It is recommended to use the camera with 4x 10x and 20x objectives as well as with a stereomicroscope. At maximum resolution video is captured at 45fps. This is enough for classroom demonstrations focus adjustment recording fast-moving processes and observing moving samples. At Full HD resolution (1920x1080pix) the rate increases to 70fps and so the transitions between frames become softer and the camera can catch the slightest movement of the sample. The camera is equipped with a USB 3.0 interface. The data transfer speed is 10 times faster than USB 2.0 cameras. The high-speed camera is recommended for professional laboratories research or university training.


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.

Key features of the microscope:

  • For viewing samples in laboratory ware up to 55mm high and a bottom thickness up to 1.2mm
  • If the illuminator stand is tilted you can use dishes up to 165mm high
  • Brightfield and phase-contrast techniques; phase-contrast condenser with a field diaphragm

  • A wide range of optional accessories

Key features of the camera:

  • 4K camera for brightfield and darkfield microscopy observations with 4x 10x and 20x objectives as well as stereomicroscope: The higher the resolution is the finer the details will be that you can see.
  • 45fps at 4K resolution 70fps at Full HD resolution: easy focus adjustment classroom demonstrations observation of moving samples and video recording - the movement of the sample can be seen without jerkiness and lags.
  • SONY Exmor backlit color CMOS sensor provides a low noise level and high light sensitivity even in low-light conditions. You will get clearer brighter and more color-saturated images.
  • USB 3.0 interface for fast smooth data transfer
  • Software with photo video recording editing external display and linear and angular measurements
