MAGUS Bio V350 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.


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: 0.2μm. 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.
