They consist of a micrometerdrive with non-rotating tip driven by a 2000 half-step/revolution, 5-phase stepper motor or a 20,000 microstep/ rev, 2-phase stepper motor. Non-Rotating Tip Compared to conventional rotating-tip micrometer drives, the non-rotating-tip design offers the following advantages: Elimination of torque-induced stage platform tilt Elimination of wear at the contact point Elimination of tip-angle-dependent wobble M-168 Stepper-Mikes feature an extremely low-stiction, low-friction construction allowing for high resolution and repeatability. A manual positioning knob provides coarse resolution of 5 µm. All models come with standard flat tips (see link for spherical tips and other options). High-Resolution Piezo Option The optional piezo tip provides 20 µm travel with sub-nanometer resolution for dynamic scanning and tracking (see link). For mounting, the Stepper-Mikes are clamped around the 19 mm diameter section. Clamping around the 16 mm diameter section should only have a supporting function; high forces at this point will increase friction and reduce accuracy and resolution. For the same reason, lateral forces on the tip must be avoided.
