Probe of the Month March 2018

This tiny stylus is almost too small for a macro lens to capture.  It's a 0.6 mm diameter ruby hemisphere mounted on a 0.25 mm diameter carbide stem.  The miniscule hemisphere was created by cutting a 0.6 mm diameter ruby sphere in half.  A typical ball-point pen holds a 0.5 mm diameter sphere.  This sphere is only 0.1 mm larger.
