SEM imaging

Imaging of the sample using scanning electron microscopy (SEM). Typically, several images are taken with varying magnifications to get a good overview of the sample. The sample can be prepared with a metallic coating for non-conductive samples. For cross-section measurement, an …

SEM-EDX imaging

Imaging of the sample using a scanning electron microscope (SEM) with energy-dispersive X-ray spectroscopy (EDX or EDS). Typically, several images are taken with varying magnifications to get a good overview of the sample. An EDX mapping, line scan, or point measurement is …

AFM surface roughness measurement

In this analysis, the surface roughness value (RMS) of the sample is determined with atomic force microscopy (AFM). The price includes three measurement points from the sample. The measurement area is 5 x 5 micrometers, if not agreed otherwise. In …

Particles size and shape analysis with image analyzer

Particle size distribution (PSD) and shapes of the particles are determined using image analysis. The method is suitable for particles sized 10-3000 µm. Image analysis characterizes particle shapes, such as fibers, rods, …

TEM imaging

Imaging of the sample with transmission electron microscope (TEM). Typically, several images with varying magnifications are taken to get a good overview of the sample. TEM allows nm-resolution images. Solid samples often require FIB preparation, which is not included in the price. …

TEM-EDX imaging

Imaging of the sample with transmission electron microscopy (TEM) and determination of the elemental composition of the sample using electron dispersive X-ray spectroscopy (EDX or EDS). Several images with varying magnifications are taken to get a good overview of the sample. …

AFM surface imaging

During this analysis, the surface of a smooth and hard sample is imaged with an atomic force microscope (AFM). Topological images are provided from several locations around the sample. The measurement area is 5 x 5 micrometers, if not agreed otherwise.

Optical microscopy

Imaging of the sample using optical microscopy. In a typical measurement, several images with varying magnifications are taken to get a good overall view of the sample.
