probe geometry

Probe geometry refers to the shape and arrangement of the probe's contact points that interact with a surface, especially in precision measurements like scanning probe microscopy. Different geometries—such as sharp tips, flat disks, or specific angles—affect how the probe interacts with the sample, influencing resolution, sensitivity, and accuracy. Understanding probe geometry helps scientists optimize measurement techniques for detailed surface analysis, ensuring reliable data by considering how the probe's shape influences contact force, imaging resolution, and signal detection.
