MAGUS Bio VD350 Biological Inverted Digital Microscope

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.

Digital camera

Video eyepiece with a SONY Exmor 8.3MP digital sensor. The sensor uses back-illumination technology to improve light sensitivity as well as to produce bright, clear images even in low light. The camera is used for work using the darkfield or brightfield microscopy technique on objectives with a magnification of 4x, 10x, and 20x. It also works with stereomicroscopes. A USB3.0 port with high data transfer speed (5Gbps) is used to connect to a computer and display images on the screen.

The MAGUS CDF30 camera is installed in the trinocular tube or in the eyepiece tube of a microscope. The maximum field of view without optical defects can be reached using an adapter with a magnification from 0.65x to 0.9x. To install it in the eyepiece tube, in addition to the adapter, you will also need an adapter matching the diameter of the tube.

The image is displayed on the computer screen with a maximum resolution of 3840x2160px. The frame rate is 45 fps. At a lower resolution (1920x1080px), the frame rate increases to 70fps. Transitions between frames are almost imperceptible, with no delays, and so the camera can be used to study and showcase moving objects. Photos and videos are recorded and saved in various formats.

Optics

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.

Illumination

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.

Accessories

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