Miniature Piezo Hexapod provides dynamic error correction.
2015-12-28 14:31:07| Industrial Newsroom - All News for Today
With 1,500 g load capacity, 6-axis Model P-915KWEF is designed for dynamic error correction for 6° of freedom. Capacitance direct metrology sensors and parallel-kinematic design with piezo actuator direct drives result in compact and stiff positioning solution. Product provides 1 nm linear resolution, 0.07 µrad angular resolution, and positioning range up to 70 µm. Mounted inside rotary stages, Model P-915KWEF virtually eliminates wobble and eccentricity errors.

Motion Controllers enhance ultrasonic piezo positioner abilities.
2015-12-22 14:31:07| Industrial Newsroom - All News for Today
Available for for positioning systems based on ultrasonic ceramic direct-drive motors (PIline®), motion controllers offer flexibility and responsiveness. Products include single-axis C-877.1U11, which is also available in 2-axis version. Digital servo circuit maximizes dynamic performance with settling times as low as few 10 msec without sacrificing resolution or smooth operation. Multi-phase controller C-867.262 allows smooth motion with velocities as small as 1 µm/sec and below.

Tip/Tilt Piezo Beam Steering Mirrors have speed-optimized design.
2015-11-04 14:31:06| Industrial Newsroom - All News for Today
Offering tip/tilt angle up to 5 mrad and optical deflection angle up to 10 mrad, S-331 platforms suit precision optics applications in ambient and vacuum environments. Precision of angular tip/tilt motion of top platform is provided around 2 orthogonal axes. Accelerations of these flexure-guided, electro-ceramic driven systems enable step response times in sub-millisecond range with frictionless backlash-free motion. Also, single pivot-point design prevent drawback of polarization rotation.
