kosketusprofiometrian

Kosketusprofiometria, also known as contact profilometry, is a measurement technique used to determine the surface topography of a material. It involves using a physical stylus that is dragged across the surface. The stylus is attached to a transducer that converts the vertical movements of the stylus into an electrical signal. This signal is then processed to create a profile of the surface, showing its height variations.

The stylus typically has a very fine tip, often made of diamond, with a radius in the micrometer range. As the stylus moves, it is kept in contact with the surface by a small force, ensuring it follows the contours. The data collected represents the surface roughness, waviness, and other geometric features. Kosketusprofiometria is a widely used method due to its relative simplicity and cost-effectiveness.

The resolution of kosketusprofiometria is limited by the tip radius of the stylus and the sampling interval. While it can provide high lateral resolution, the vertical resolution is generally excellent. It is particularly suitable for measuring relatively flat and smooth surfaces. Applications include quality control in manufacturing, characterization of coatings, and analysis of worn surfaces. However, it is not suitable for very soft or fragile materials as the stylus can potentially damage the surface. It also cannot measure features that are smaller than the stylus tip.
