A stereomicroscope is an indispensable tool for the detailed study of volumetric samples. It reproduces the virtual volume of an object and allows you to examine its structure, thereby providing a clear image of its topography. The device is equipped with transmitted and reflected light illuminators and allows you to work with both transparent and opaque samples. Polarized light and darkfield methods are optionally available.
The advantages of the Greenough optical design are the large depth of field and three-dimensionality of the image due to the stereoscopic angle of 15°. A stereomicroscope magnifies an object and accurately conveys its position in space: the image is formed uninverted. This makes the microscope an ideal tool for manipulating objects within a working area of 105 to 177 millimeters. Stereomicroscopes are widely used for quality control in restoration, assembly, soldering, jewelry work, and similar processes.

The head of the MAGUS Stereo 7B microscope features 2 eyepiece tubes. If you need to connect a digital camera, it is inserted into one of the tubes. To set up comfortable and effective observation, the head can be rotated up to 360° and fixed in any intermediate position. The microscope comes with 2 eyepieces with 10x magnification and a field of view of 22mm. Diopter adjustment can be made on the eyepieces, and for those who wear glasses, the eye relief is positioned at a convenient distance.

The zoom objective changes the magnification of the subject by 6.7x without letting it out of focus. The image is formed in volumetric and upright form. You can add magnification or field of view as well as change the working distance using auxiliary objective lenses of different magnifications.

MAGUS Stereo 7B model only features coarse focusing. There are two focusing knobs that are located on both sides of the stand. The travel stiffness can be adjusted.

The stage is equipped with two different plates. The transparent one is for working in transmitted light. It scatters light, and so the object receives uniform and soft illumination. The second plate is black-and-white. It is installed on the stage according to the principle of contrast to the object of observation and is used for opaque samples.

The microscope is equipped with illuminators for transmitted and reflected light. Reflected light forms oblique lighting. Both illuminators are based on 3W LEDs with a lifespan of 50,000 hours.

The microscope is complemented by a wide variety of additional components that can be purchased separately. The range includes eyepieces and auxiliary objective lenses: They provide different magnifications, change the field of view and the working distance of the microscope. Digital cameras with broad functionality will allow you to display images on the screen or document your observations. To measure objects, you can purchase calibration slides. For studies using the darkfield method or in polarized light, the microscope can be equipped with a darkfield condenser and a polarization device, respectively. For even broader functionality of the microscope, there are a number of different illuminators: classic ring, ring with a polarizer or sector switching, and a gooseneck type. A variety of stands will allow you to choose the optimal microscope head position above the working surface and expand the working space.
