White light interferometer

The white light interferometer is a high-precision instrument used in surface topography to provide detailed information about the geometry and nature of surfaces. In contrast to conventional interferometers, the white light interferometer uses broadband light, which makes it particularly powerful.

The basic idea behind the white light interferometer is the interference of the incident light that is reflected by the surface. By analyzing the interference patterns, precise measurements of height differences on the surface can be made. This enables precise characterization of microstructures, unevenness and other topographical features.

Applications for the white light interferometer span a variety of industries, including semiconductor manufacturing, materials science, optics and microsystems technology. Its high resolution and accuracy make it an indispensable tool for quality assurance and research in areas where precise knowledge of surface topography is critical.

By precisely capturing topographical details, the white light interferometer enables progress in the development of new materials, quality assurance of manufacturing processes and research into micro and nano systems. It therefore makes a significant contribution to the further development of technologies based on fine surface properties and structures.
