San Francisco, CA — 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. The new ultra-low profile (0.6”), direct-driven, high-speed rotary stage is based on PI’s proprietary PILine® piezomotor drive technology.
The M-660 PILine® rotation stage allows high positioning speeds to 720 degrees /sec. It also features a very low profile of 15 mm (0.6") and a 35 mm Ø clear aperture
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.
Nanopositioning Stage for Super-Resolution Microscopy

Auburn, Mass. – The nano1×3 ™ series X-Y and X-Y-Z nanopositioning stages from PI (Physik Instrumente) are multi-axis stages for super-resolution microscopy applications, providing highly accurate motion with closed-loop control for sub-nanometer precision over travel ranges of 200µm in X-Y and X-Y-Z planes.
The stages feature a piezo controller and comes with three, 24-bit digital interfaces (USB, TCP/IP, and RS-232) and a wide-band analog interface for compatibility with all control signals. With 24-bit DAC converters, commanded resolution is improved by two orders of magnitude over the still widely used 16-bit converters. The controller is also compatible with all major image acquisition packages and comes with a wide variety of software drivers and programming examples.
For highly stable, closed-loop operation, piezoresistive sensors are applied directly to the moving structure of the stage and precisely measure the displacement of the platform. The very high sensitivity of these sensors provides optimum position stability and responsiveness as well as sub-nanometer resolution. The proprietary servo circuit significantly improves the motion linearity compared to conventional piezoresistive sensor controllers.
