The Surface Profile Analyzer SPA 25 utilises white-light interferometry for studying
the surface topography and roughness parameters with exceptional speed and enable
the system to achieve a height resolution of down to 0.1 nm even with small
magnification factors. When it is used in combination with an optical contact angle
measuring system of the DataPhysics OCA series, such integration provides further
insight into surface properties by e.g. determining the surface corrected contact
angle according to the Wenzel theory.
The SPA 25 instrument comes with the industry leading MountainsMap® Imaging
Topography software providing a comprehensive set of tools for the analysis of the
studied surface. The software allows instrument to create 3D maps of large surface
areas (up to 300 mm x 300 mm with automated sample table) and to detect defects
caused by material processing and treatment. The surface roughness can be analysed
according to various industry standards like ISO 25178, ISO 4287, ISO 13565, ISO
16610, etc.
