Q-Mark Product Spotlight: Small Calibration Spheres

Small Calibration Spheres

Small diameter calibration spheres are essential when qualifying small diameter styli.  They allow the stylus to reach more of the sphere’s surface, giving better qualification values.  They also reduce the possibility of “shanking out” the stylus during qualification.  This helps reduce breakage.

Shown here are 5.0 and 8.0 mm ruby calibration spheres.  They are Grade 5, serialized, and furnished with laboratory certs as to form and diameter.  Their stainless steel stems have M6 threads.

We offer Grade 5 calibration spheres in diameters ranging from 5.0 mm to 30.0 mm. When qualifying small diameter tips, always use a small diameter calibration sphere.
