Among the many models of Leica microscopes, there is such a Leica microscope suitable for testing with or without prepared samples, which is the Leica DVM6 M 3D digital ultra depth of field intelligent microscope. Under appropriate accessory conditions, the microscope can be transformed into a semi quantitative polarization microscope.
Geoscientists can use such a polarized Leica microscope to analyze geological samples, whether they have been prepared or not.
Diversified geological samples require a series of qualified microscope solutions:

The Leica DVM6 microscope is suitable for analyzing these types of geological samples and is almost applicable to all geological detection projects.
Why does this Leica microscope have such a powerful range of application?

Is the installation of Leica DVM 6 M on a high and stable manual or electric focusing column an additional increase in working distance? This ensures that geologists can detect and observe polished or unpolished samples.
The transmission light holder with high numerical aperture is suitable for digital solutions in diverse polarized light applications.
Provide a polarizing stage for the transmission base, with a rotating in/out polarizing mirror on top.
By configuring the Leica DVM6 M Leica microscope according to the above method, it is difficult for sample analysis in any geological science application field, and it can also ensure that users can observe transparent samples under parallel and cross polarized light separately. Whether the sample is equipped with a cover glass or whether it is an uncut transparent mineral (such as diamonds or indicator minerals) can be determined. The functionality is really powerful! In addition to these, there are even more powerful advantages. Let me give you a sun exposure.
The Leica DVM6 M Leica microscope has so many powerful functions and can also improve the work efficiency of geological scientists, attributed to the following advantages:
A Leica microscope can flexibly process samples that have been or have not been prepared;
The lighting system fully integrates annular light, coupled with coaxial and other types of lighting, ensuring that the options for studying and analyzing samples far exceed those of a compound microscope;
Efficient and fast switching of magnification throughout the entire range;
The software is intelligent and intuitive, making it more suitable for microscope operation and analysis;
The automatic tracking and storage (encoding) of important parameters ensures the reproducibility of microscope detection and the ability to quickly call up imaging conditions.
The Leica DVM6 M Leica microscope can perform excellent observation and analysis on both prepared and unprepared samples.
The following is a prepared basalt thin section sample. The Leica DVM6 M microscope uses polarized light illumination from different directions to clearly display the structure and composition of basalt.

You can also use the Live Image Builder function in Leica DVM6 M microscope software. During the stage of stage scanning, a single image is created through the synthesized image recorded by the camera, ensuring that users can view the sample on a larger scale.

For reflection, built-in coaxial lighting can also be used to observe polished samples without the need for additional components. In reflected light mode, adjust the built-in¼ λ Plate (wave plate) can complete the polarization light crossing.

The Leica DVM6 M microscope is equipped with a tilted illumination slider in coaxial illumination mode, providing three-dimensional images of grain boundaries, hardness differences, and scratches. Simply move the lighting slider to observe the sample.

The image on the right shows the detailed image of the sample obtained by the Leica DVM6 M Leica microscope equipped with integrated annular light. Although traditional polarized light microscopes do not have a dark field, the Leica DVM6 M equipped with annular light provides additional dark field angles for polished samples.
In addition to the observation of earth science samples mentioned above; Classic; In addition to methods, Leica DVM6 M Leica microscope can also be used to observe three-dimensional images of samples not prepared, such as microscopic slides, core parts, scattered minerals, Microfossil, etc.

The built-in circular light setting or gooseneck spotlight of a stereoscopic microscope allows for observation of unprepared samples in a similar manner to that of a stereoscopic microscope. However, for samples with a thickness exceeding the depth of field of the microscope, it is very easy to observe them using the multi focus function, and then reconstruct the three-dimensional morphology of the sample. If only 2D images are needed, the Live Image Builder feature can be enabled. The Leica DVM6 M Leica microscope software features Live Image Builder Z (equipped with manual focusing column) and Montage options (custom, EDOF, startup), providing a very simple way to obtain multifocal images, which is both intelligent and user-friendly.
For samples such as loose surfaces, rocks, and cores, the field of view provided by the microscope is usually larger. Equipped with Live Image Builder XY, limitations can be overcome and multiple images can be synthesized into a single image with a larger field of view. The three objective lenses have magnification (1x~2350x) and resolution, which can quickly switch between macro and micro images of larger samples. All images can be automatically calibrated for measurement. In 3D morphology reconstruction, surface characteristics and volume can also be measured.

Leica DVM6 M-type 3D ultra depth of field digital Leica microscope combines Microcosm–macrocosm analogy into one, ensuring that both 2D and 3D samples can be analyzed. Due to the simultaneous increase in field of view and depth of field, it is easy to manipulate samples of different heights. Leica DVM6 M microscope is more suitable for analyzing geological samples, and geological scientists choose it.
