M-631, M-632, M-633
M-631 through M-633 micrometer drives feature an extremely low stiction/friction construction allowing for ultra-high resolution. The non-rotating tip design offers the following advantages over conventional rotating tip micrometer drives:
- 10, 25 and 50 mm Travel
- Pitch 0.5 mm/Rev.
- Low Friction Construction
- 1 µm Manual Sensitivity
- Sub-nm Resolution with Optional PZT Actuator
M-631 through M-633 micrometer drives are also employed in the PI DC-Mike and Stepper-Mike motorized actuators featuring sub-micron resolution (see page 7.46, 7.48). All models come with standard flat tips. click here for spherical tips and other options.
- elimination of torque-based stage platform tilting
- elimination of wear at the contact point
- elimination of tip angle dependent wobble
An optional piezo tip provides 20 µm travel with sub-nanometer resolution for dynamic scanning and tracking (click here).
For mounting, the micrometers are clamped around the 19 mm diameter. Clamping around the 16 mm diameter sleeve 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.
