Description

MAGUS Bio 250B biological microscope is an optical instrument used for studying thin transparent and translucent objects. Brightfield microscopy in transmitted light is the main microscopy technique. The microscope can be equipped with additional accessories for using darkfield, phase contrast, and polarization techniques. High-quality optics with additional options to expand its capabilities, easy-to-use mechanics, and smart design make this microscope an excellent choice for lab work, research, and teaching.

Optics

The binocular head allows you to mount a digital camera in one of the eyepiece tubes (camera not included). The tubes can be rotated 360° to obtain a comfortable position to fit the height of the observer. The diopter adjustment ring is located on the left tube.

The revolving nosepiece allows for mounting 5 objectives. The microscope comes with infinity plan achromatic objectives that provide clear, high-contrast images across the entire field of view. There is a single free slot in the revolving nosepiece for mounting an additional objective. The revolving nosepiece with objectives is oriented toward the interior so that the user can see the objectives inserted into the optical path, and the space above the stage is free.

The microscope optics in the basic configuration provides magnification from 40 to 1000x. The use of additional eyepieces, if necessary, allows you to increase the upper limit of the magnification range.

Illumination

Light source: 30W halogen bulb. It provides uniform and bright illumination of the sample using any objective lens and any observation method, including darkfield and phase contrast techniques. The warm spectrum of light is pleasing and comfortable for the eyes, so they will not get tired even when working with the microscope for long periods of time.

The Abbe condenser has a slot for mounting a darkfield or phase slider. The condenser design simplifies and speeds up the process of switching research techniques. The condenser is height-adjustable and can be centered. The field diaphragm makes it possible to set up the Köhler illumination.

Stage and focusing mechanism

The stage is equipped with a mechanical attachment that can be removed for manual scanning. There is no positioning rack that ensures the ergonomic operation of the stage.

Focus adjustment is adjusted by the coaxial coarse and fine focusing knobs on both sides of the microscope body. The mechanism is smooth and precise, and no effort is required to rotate the knobs. The coarse focusing has a lock knob and tension adjustment. The focusing knobs are located at the bottom. Therefore, you can rest your hands on the table rather than holding your arms in the air. It increases comfort during long work sessions.

Accessories

A wide range of accessories allows the MAGUS Bio 250B to be configured in the most convenient way for the user. Eyepieces, lenses, darkfield, phase contrast and polarization devices, calibration slides, and digital cameras are available.
