Commonly referred to as a mushroom stylus, this design uses the entire surface of the hollow hemisphere for large-contact measurements, making it well-suited to probing coarse textures and low-feature features.

The hemispherical design provides full-surface contact, reducing measurement bias on rough textures and enabling consistent data capture across larger contact areas. The ceramic ball offers wear resistance and smooth interaction with challenging surfaces, while the stainless steel base delivers durability in daily inspection and scanning workflows. This combination is especially effective for tactile probing on metals, castings, and components with pronounced texture.
