New Miniature Hexapod for Photonics Alignment provides Dynamics and Precision, and Automated Alignment Algorithms

(Nanowerk News) PI has added a high dynamics model to its range of compact hexapods. Designed for photonics alignment applications, the hexapod provides 6 degrees of freedom, actuator resolution of 5 nanometers and repeatability as good as 60 nanometers, while providing velocities to 20mm/sec. Sustaining loads to 5kg, the new H-811.F2 features a removable magnetic kinematic plate to accelerate workflow with different fiber optics components. Its compact size, large travel range of up to 34mm for linear motions and up to 42 for rotary motions, and a user programmable pivot point facilitate work with fiber optic and photonics components.

High Duty Cycle Design for Industrial Alignment

The hexapod is designed for industrial precision alignment applications with long-life brushless motors and low friction ballscrews and joints. A powerful controller with build-in multi-axis alignment routines makes the new hexapod an ideal tool for automatic alignment tasks.

How do Hexapod Parallel Motion Systems work?

Hexapods are 6 DOF positioning / motion systems that derive 6-axis movement (XYZ, pitch, yaw, roll) from actuators placed in parallel between a top and bottom platform. Available in a variety of sizes with bases ranging from 50mm to 1m and different load capabilities up to 2 tons, PI hexapods are an easy solution to complex multi-axis precision motion applications. PI hexapods come with state-of-the-art controllers and software tools based on 25 years of hexapod R&D, resulting in fast solution implementation to a plethora of applications from medical to photonics. All 6 axes can be commanded simply as Cartesian coordinates, and the center of rotation can be changed on the fly with a software command. Other advantages are the absence of friction and torque, caused by dragged cables.
