The microscope is designed for studying the microstructure of metals and alloys semiconductor materials and other opaque specimens.
The design of the inverted microscope does not limit the size of the examined sample; only its weight is limited up to 30kg. The specimen must be first specially processed and then it is placed on the stage with the surface down.
This microscope can study opaque objects in reflected light using the brightfield darkfield polarization microscopy and differential interference contrast techniques.
DIC is an advanced polarization contrast technique. The method increases the depth of field and image clarity provides additional information about the structure of the object under study and visualizes irregularities on the studied surfaces with color. Flat surfaces are painted equally but a surface with even minimal differences in height will be uneven in color. The object of study will appear in relief.
The microscope can be used in various fields (metallurgical engineering aerospace nuclear and energy industries) as well as in research laboratories and technical universities.

Microscope head

Trinocular head with infinity-corrected optics. The 45° tilt angle provides comfortable conditions for the researcher to work while sitting or standing. The user can assume a natural pose and therefore fatigue does not accumulate during the workday.
A Bertrand lens is built into the microscope head; a regulator on the front of the head is used to insert it into the optical system. The Bertrand lens is used for conoscopic studies.
The digital camera is installed in the trinocular tube or in one of the side imaging ports on the microscope body. The beam on the trinocular head can be split 100/0 50/50 or 0/100. The beam splitting on the right photo port is 100/0 and 20/80; it is 100/0 and 0/100 on the left.
The basic package includes 10x/23mm eyepieces with diopter adjustment and long eye relief for working with glasses.

Revolving nosepiece

The 5-objectives revolving nosepiece is mounted on the stand under the stage. The differential interference contrast method is implemented using DIC sliders: One is used with low magnification objectives and the other with medium and high magnification objectives. The DIC slider is installed in a special slot of the revolving nosepiece.

Turret for installing contrast modules

Under the objective revolver on the microscope stand there is a turret for installing contrast modules. Six modules can be installed. Rotating the turret changes the observation mode switching from one contrast method to another occurs quickly and without complex settings.

Switch with an additional magnification lens

A rotary switch is used to insert the main 1x lens or an additional 1.5x magnification lens into the optical path. A magnifying lens increases the magnification of a microscope without purchasing or installing additional accessories. The switch is located on the right side of the microscope body under the revolving nosepiece.


Semi-apochromatic objectives with a long working distance that are designed for the brightfield and darkfield microscopy techniques. Provide better correction of chromatic and spherical aberration compared to plan achromatic objectives.

Focusing mechanism

Coaxial coarse and fine focusing knobs are located at the base of the microscope on both sides. The right fine focusing handle has special recesses for fingers and the left one has a scale.
The coarse focusing lock knob helps you quickly adjust the microscope after changing the subject of study. The knob is located on the left side of the microscope on the same axis as the focusing mechanism.
The ring on the right side adjusts the tension of the coarse focusing travel. The user adjusts the comfortable tension for work.


The object is moved by moving the stage along two axes. An insert with a hole of a suitable diameter is installed in the center of the stage. A specimen holder is used to hold the object in place.
The three-layer coating protects the stage from scratches and other surface damage when working with heavy and large samples.
The long tiltable stage control handle ensures user comfort while working: The hand rests on the table without strain. The handle can be installed on the right or left side of the stage.

Light source

The lamphouse has a 100W halogen bulb. It is bright enough to work on objectives with magnifications from 4x to 100x not only in brightfield and polarized light but also in darkfield microscopy techniques. The halogen bulb emits light with a color temperature that allows for comfortable work.

Reflected light illumination

The illumination system makes it possible to set up the Köhler illumination. The field and aperture diaphragms are pre-centered at the factory and require no additional centering. If necessary the diaphragms can be adjusted with centering screws.
The analyzer and polarizer are for the polarization microscopy technique. The polarizer is stationary and the analyzer rotates 360°.
A set of light filters helps you adjust color reproduction.

Ergonomic design

Physical discomfort causes fatigue and reduces productivity. The ergonomic design of the microscope plays an important role in everyday scientific research. The MAGUS Metal V790 DIC provides user comfort during work.
The microscope is operated with minimal hand movement since the long stage control handle and fine focusing knob are located in the same working area.
Focusing knobs are located at the bottom of the body. The user does not strain their hands. Thanks to the smooth movement of the mechanism the user can effortlessly focus on the object.
