V-931: Fast Steering Mirror for Laser Optical Communication and Laser Beam Control
Voice coil motors are direct drives conveying the force of the drive element directly to the load without using mechanical transmission parts, such as a coupling, drive screw, or gearhead.
Voice coil drives are made up of a permanent magnet and a winding body positioned in the magnetic field’s air gap.
The winding body moves when current flows through it, causing the permanent magnet’s magnetic field to change.
Voice coil drives are particularly well suited for applications with high dynamics and velocities at constrained travel ranges due to their low weight and friction-free drive mechanism. These drives are free from the effects of hysteresis, enabling high scan frequencies and precise positioning.
Features
Compact design
Durable and friction-free thanks to flexures
Noncontact direct position measuring with linear encoders
Beam deflection angle to 8°
Two orthogonal tip/tilt axes with a common center of rotation
Identical motion characteristics of both axes thanks to parallel kinematics
V-931.01, dimensions in mm. Image Credit: PI (Physik Instrumente) LP
High Dynamics Multi-Axis Operation Due to Parallel Kinematics
All actuators in a parallel-kinematic multi-axis system operate on a single platform. The axes’ uniform designs and low mass inertia make fast, dynamic, and precise motion possible.
Application Fields
Test and inspection: AOI (automated optical inspection),noncontact profilometry, sensor testing
Optics: Optical filters/switches, optical trapping, grid scan, tracking
Beam stabilization
Satellite communication
Image processing/stabilization
Laser micromachining. Laser tuning andlaserscanning/beam steering with large deflection angles
