Description of equipment

The Keyence VHX-7000 high-resolution digital microscope with integrated moving head and sample analysis and measurement software is an optical microscope with a high depth of field and advanced measurement functions.

The microscope is equipped with a high-resolution camera with a 4K CMOS sensor in an integrated head that allows tilting of the viewing axis and rotation around the object for a full 360-degree view in 2D as well as 3D. It features a wide range of magnifications; optical magnification from 20 to 500x and digital magnification up to 2500x (4x digital zoom). The microscope can be used in reflected light, transmitted light, polarised light and dark field.

It features high depth of field, advanced measurement functions, an easy-to-use user interface and state-of-the-art technology for sample analysis and 2D and 3D measurements that can be performed on-screen in real time. Features include measurement of point-to-point distances, angles, diameters, parallels and areas using the automatic edge detection function. Automatic analytics include grain counting, grain size analysis and ISO surface cleanliness analysis.

Access to equipment of equipment

Regional Geology, Mineral Resources and Groundwater and Geochemistry programme groups, various research and commercial projects.

The digital optical microscope is useful for petrographic, sedimentological and palaeontological investigations. It is also useful for the analysis of environmental media, archaeological artefacts and other materials. The fast automatic 2D or 3D image compositing function allows the scanning of petrographic debris and large samples.

Equipment rental

The use of the microscope is reserved for GeoZS researchers and is only possible in the GeoZS microscopy room. We also carry out microscopic research for external clients by arrangement. The price is determined by the GeoZS internal price list or by agreement.
