Styli Standard

Spherical styli have the largest field of application because they have the same probing behavior in every direction. They are therefore suitable for all common measuring tasks such as measuring bores and surfaces. The larger the stylus sphere size, the larger the mechanical filter. This means that the profile of your workpiece is smoothened, which is often required in form measurement. The deviation from the ideal sphere shape is usually shown in Grade. ZEISS styli spheres have Grade 5 as standard, but can also be offered in a higher Grade 3 for special requirements. Styli with a straight shaft are the most simple designed styli. The full shaft length can be used as measuring length. Stepped shaft has the advantage of a greater shaft thickness, which is reduced towards the measuring tip. This stepped shaft increases the stability of the shaft while maintaining the same length (depending on the sphere diameter). At the same time, however, the usable measuring length is reduced.
