N81 Linear Piezo Motor
The linear piezo motor has the resolution of more than 20nm in full stroke, rated load of 25N, compact design, excellent long-term stability, and can continue to remain at the set position in the event of a power failure.
It can be used for touch-free adjustment of hard-to-reach optical adjustment frames, and adjustment of optical frames that are sensitive to force when turning the knob (such as laser cavity adjustment or long distance beam pointing adjustment).
Features
- Min step:<20 nm
- Compact design
- Self-locking at rest, requires no current
- Lifetime > 1 billion steps
