With the Beetle Design, the tip moves with the sample, virtually eliminating effects of thermal drift.

As showing ot the right, the 1-Dimensional problem of sample movements into the tip gap are virtually eliminated. Additionally, 3-D problems of mechanical expansion and contraction are lessened by the fact that the tip is precisely centered on the sample holder.



Symmetric geometry provides first order thermal drift compensation in all three axes, eliminating the need for complex compensation software.
