PI (Physik
Instrumente) L.P. introduces a new ultra-low profile (0.6"), direct-driven,
high-speed rotary stage based on its proprietary PILine piezomotor drive
technology at this year's SPIE Photonics West conference.
Fast, Self-Locking, Direct Drive, Direct Encoder
The M-660 stage reaches top speeds of 720 degrees/sec. and resolution to 40
µrad (8 arcsec). Its self-locking ceramic drive holds the position steady
at rest, with no energy consumption and heat generation. A directly coupled
precision optical encoder provides phase lag-free, backlash-free feedback to
the servo controller.
Ceramic Drive Used in the Latest Generation Optical Instruments
The compact design with minimized mass and inertia, provides high precision
bidirectional speed and position control, as well as high speed motion contouring.
The M-660 outperforms the stability, acceleration and settling speed of traditional
servo motor direct drives and gear-driven mechanisms.
The innovative motor drive was also chosen by Leica Geosystems AG in their
newest generation of surveying instruments for geodesy, because it can provide
significantly higher speeds, shorter positioning times and a very high positioning
accuracy when moving the measuring optics. A video demonstration is available
