Sub-micron drift can quietly undermine even a well-designed optical assembly line, especially when aligning miniature lenses or photonics components where tolerances leave no room for error. PI’s six-axis hexapod platform is built around exactly that problem, holding platform position within 3 nanometers while resolving individual actuator motion down to 1.4 nanometers — precision aimed at applications like fiber-to-chip alignment in silicon photonics, where drift on that scale can mean the difference between passing and failing a coupling test.

Key Specifications

• Actuator resolution: 1.4 nm
• Platform in-position stability: 3 nm
• Linear travel: up to 34 mm (XYZ)
• Rotary travel: up to 42° (pitch, yaw, roll)
• Payload capacity: 5.5 lb
• Velocity: up to 20 mm/sec
• Software-adjustable pivot point

Full specs are available on the H-811.S2iHP datasheet.

Long-duty-cycle reliability comes from low-friction ballscrews, precision joints, and brushless motors rated for continuous industrial use. Firmware-level alignment routines automate first-light detection, peak-tracking, and array alignment, cutting the manual tuning multi-channel photonics setups typically require — learn more on these workflows in PI's hexapod applications blog.

Built by PI for test, assembly, and automation across optics, photonics, silicon photonics, and microscopy, the H‑811.S2iHP is available now; engineers can book a hexapod demo to evaluate it directly.
