Abtastspitze

Abtastspitze is a German term that translates to "sensing tip" or "stylus" in English. It refers to a component used in various measuring and recording devices to detect and translate physical phenomena into electrical signals. These tips are designed to interact with a surface or medium and convert variations in its properties into a measurable output.

The design and material of an Abtastspitze vary greatly depending on its application. For example, in record players, the Abtastspitze, commonly known as a stylus or needle, traces the grooves on a vinyl record. Its precise shape and material are crucial for accurately reproducing the audio information etched into the record. In scientific instruments, such as profilometers or atomic force microscopes, the Abtastspitze is a very fine probe used to scan surfaces at a microscopic level, measuring topography, friction, or other surface characteristics.

The interaction between the Abtastspitze and the surface is often mechanical, involving physical contact. However, non-contact sensing tips also exist, utilizing optical, magnetic, or capacitive principles. The sensitivity, accuracy, and durability of an Abtastspitze are critical performance factors that depend on its construction, the materials used, and the precision of its manufacturing. The term is broadly applicable to any finely shaped element designed for sensing or tracing.
