Hemispherical stylus
Hemispherical stylus are suitable for measuring elements requiring a large diameter of the probe ball with low weight or reduced overall height, as opposed to disc probes, which only allow radial probing. The hemispherical stylus probes can also be used to measure the stem direction. The advantage is that the entire surface of the hollow hemisphere can be used for probing.
