Ultra-High-Resolution Hexapod for Photonics & Optics Alignment
The new H-811.S2iHP high-resolution / high-stability compact hexapod was designed specifically for the precise alignment of high-resolution miniature lenses and photonics components. The hexapod utilizes six low-friction, long-life actuators and 12 precision cardanic joints with offset axes, ensuring enhanced stiffness.
Higher Resolution and In-Position Stability
This hexapod is engineered to achieve superior precision and stability. Its actuators provide a resolution of 1.4 nanometers, and the platform delivers in-position stability of 3 nanometers.
Automating 6-Axis High Precision Motion Tasks
With a linear velocity of 20 mm/sec, rotary velocity of 28°/sec, fast acceleration, and a load capacity of 5.5lbs, the H-811.S2iHP is ideal for automating tasks such as alignment, testing, and assembly of miniature optics and photonics components. Despite its compact size, it offers linear travel ranges up to 34 mm in XYZ and rotary motions (pitch, yaw, and roll) up to 42°. A user-programmable pivot point further facilitates alignment of lenses, fiber optics, and photonics systems.
Dynamic Operation
The hexapod also provides excellent dynamic properties. »Dynamic operational range data
High Duty Cycle Design for Industrial Alignment
Designed for industrial precision alignment applications, the hexapod incorporates low-friction precision ballscrews, precision joints, and long-life brushless motors to ensure reliability and durability.
Advanced Controller for Alignment Optimization
The H-811.S2iHP is paired with a powerful hexapod controller featuring advanced multi-axis alignment routines at the firmware level. These routines enable tasks like first light detection, optimization, tracking, and array alignment, making the hexapod an ideal tool for automated photonic and optical alignment tasks.
Hexapod Parallel Motion Systems: How do they Work?
Hexapods are 6-degree-of-freedom (6 DOF) motion systems capable of movement in XYZ and rotations in pitch, yaw, and roll. They are based on actuators arranged in parallel between the top and bottom platforms and controlled by a powerful controller handling the hexapod kinematics – so the user only needs to send commands in common Cartesian coordinates.
Available in various sizes, from base diameters of 100 mm to 1 meter, and load capacities up to 2 tons, PI hexapods are versatile solutions for complex multi-axis precision motion needs. Equipped with state-of-the-art controllers and software tools PI hexapods are based on 30+ years of continuous improvements and enable fast and precise implementation across diverse applications, including aerospace technology, medical devices, semiconductor technology and photonics.
