6-axis nanopositioning system assembly provides the ultra high
precision required to mount and align optical components to be
launched into space, new from PI.
AUBURN,
Mass., May 8, 2024 /PRNewswire-PRWeb/ -- PI, a
global leader in nanopositioning and motion control, continues
to contribute to space exploration advancement as PI 6-DOF hexapods
deliver the precision required by the Laser Interferometer Space
Antenna (LISA) project. LISA is a space-based gravitational wave
observatory, that will detect cosmic undulations from black holes
with much greater resolution than the much smaller earth-bound
systems are capable of. The interferometer, based on three
spacecraft, 2.5 million kilometers apart, is constructed of the
highest accuracy components, including optical components precisely
aligned with the help of the hexapod.
ESA, NASA, and PI Hexapods – Working Together, Again
During the assembly of the ultra-precision optical components at
the heart of the LISA project expected to launch in 2035, UKATC
engineers employ precise control in 6 degrees of freedom with PI's
compact H-824 hexapod (Stewart Platform). Hexapods, with their
programmable center of rotation (pivot point), are the gold
standard when it comes to precise multi-axis alignment tasks, from
nanometer sized structures in silicon photonics / fiber optics to
big mirrors and reflectors in astronomy. Based on 4 decades of
experience, PI hexapods are available in many different sizes and
configurations. They are supported by a host of software tools,
alignment routines, and accessories. The great flexibility allows
the hexapod user to adapt their 6-axis motion system to any
alignment application quickly without retooling.
H-824 Features
- Compact: 281mm base, 190mm height
- 45x45x25mm XYZ travel
- 15x15x25° rotary travel
- Up to 10kg load
- Up to 25mm/sec max. velocity
Hexapod Controller / Motion Software
PI's hexapod controllers and hexapod software are based on decades
of experience with parallel kinematic motion systems. PI's free
hexapod software simulates the limits of workspace and load
capacity, thereby ensuring the hexapod you choose will handle the
loads, forces, and torques in your application.
