The following equipment is used in the field of microscopy:
In Vickers hardness testing, a force is applied uniformly and without impact to a specimen with a diamond indenter. The Vickers diamond creates an indentation in the shape of a pyramid with a square base, with an indentation depth of approximately 1/7 the length of the diagonal. The force applied through the indenter is maintained for approximately 10 to 15 seconds, followed by complete unloading. The two indentation diagonals are measured and then averaged. The Vickers hardness (HV) is calculated using a formula.

Technical specifications
Magnifications from 2x to 1.000.000x
Field Emission Cathode

Large sample chamber GM 340x320x310mm
Integrated plasma cleaner and liquid nitrogen cooled (-196 C°) cold trap
Applications
This reflected-light microscope is used to perform and document microstructural analysis, microsection control, or cleanliness evaluations. The calibration of a camera, the different adjustable magnification options, give the operator the possibility to insert accurate measurement bars into the images. The instrument is also equipped with a polarization filter to detect any unevenness on the specimen surface. These can then be compensated for by the multifocus integrated in the software.
Technical specifications
Applications
The Leica M80 stereomicroscope is used to examine and document larger and unprepared specimens. With interchangeable objectives, as well as freely adjustable zoom and exposure levels, the microscope offers a wide range for macro and micro images. By calibrating a camera to the various adjustable magnification levels, it is possible to introduce a dimension bar with measurement accuracy into the images.
Technical specifications
Applications
Specimens can be examined and imaged with an extremely high resolution on the DM6 M light microscope from Leica. The parameters set during an exposure can be saved and reloaded for later exposures. In addition to the features of the other light microscopes, the Leica can scan a larger sample area and automatically stitch it together to generate a high-resolution overview image. With full automation of the operating parameters, the microscope can also be controlled remotely, allowing specimens to be viewed via live transmission.
Technical specifications
Applications
The Isomet 5000 enables millimeter-precise cutting of filigree specimens. Various fine cutting wheels and cutting parameters can be selected for different toughnesses. The constant flow of cooling water ensured by a pump system, as well as the automatic adjustment of the feed speed in case of too high strengths, ensure the lowest possible influence on the specimen material.
Technical specifications
Applications
Both Vickers and Brinell hardness can be determined on Wolpert hardness testers. The indenter, consisting of a hard metal ball or diamond pyramid, penetrates the surface of a plane-parallel specimen without impact and creates an indentation in the material. The indentation is then projected onto a ground-glass screen integrated in the device, from where it can be measured and evaluated with the aid of an enclosed scale. The Brinell indenter is particularly suitable for softer materials, and the Vickers indenter for harder materials.
Technical specifications
Applications
In order to ensure a plane-parallel and scratch-free specimen surface, two Phoenix 4000 semi-automatic polishing machines are used. By means of an exchangeable specimen holder, up to 6 embedded specimens can be ground and polished simultaneously. During the grinding and polishing process, parameters such as contact pressure, direction of rotation, rotation speed and polishing time can be adapted to the individual specimen material.
Technical specifications
Applications
Up to two embeddings can be performed simultaneously in a short time on the Opal 460 hot embedding presses. The sample to be embedded is placed on one of the plungers and encapsulated in an added plastic granulate during the process. Parameters such as pressure, holding time, or temperature can be freely adjusted to the desired embedding material. The embedding process significantly simplifies the handling of more complex specimen geometries for further preparation. By using a conductive mounting medium, the specimens can be easily examined under a scanning electron microscope after preparation.
Technical specifications
Applications
With the KLS 05/13 laboratory chamber furnace, heat treatments with up to 1300°C can be carried out. A built-in switching and control system allows the desired temperature sequences or holding times to be precisely set. An external protective gas connection ensures that the heated sample material does not oxidize during the heat treatment.
