PI (Physik Instrumente), a global leader in precision motion control solutions, announces the release of the F-690.S1 SpaceFAB, a high-performance 6-axis motorized positioning stage platform, designed for advanced automation tasks that demand high speed, precision, and reliability.
Low-Profile 6-DOF Architecture for High Dynamics and Repeatability
The F-690.S1 is built on a unique hybrid kinematic design featuring three symmetrically arranged XY nanopositioning stages with direct-drive linear motors and cross-roller bearings. Each stage supports a linear bearing mounted on a wedge with ball-joint connections, enabling full 6-degree-of-freedom motion (X, Y, Z, pitch, yaw, roll) with smooth coordination and minimal mechanical crosstalk.
Absolute encoders provide 1 nanometer resolution, while pneumatic brakes ensure positional safety during power loss. The compact, low-profile system supports payloads up to 2kg and is capable of operating in inverted orientations, making it ideal for space-constrained or vertically integrated setups.
Integrated Electronics for Real-Time Precision Motion Control and Coordinate Transformation
At its core, the SpaceFAB features an ACS-based SPiiPlusEC motion controller with ultra-low-jitter NanoPWM drives and 24-bit A/D converters. This platform enables fast, precise motion with high dynamic range and minimal noise. The controller handles inverse kinematics internally and supports Cartesian commands for simplified system integration.
Features like software-defined pivot points (“Pivot Anywhere”) make the F-690.S1 adaptable to a wide range of automation tasks — from micro-assembly and PIC component testing to high-precision metrology — where multi-axis accuracy and throughput are critical.
Alignment Routines for Production-Scale Throughput
The SpaceFAB motion and alignment controller comes preloaded with a comprehensive suite of high-speed photonics alignment routines, including:
- FMPA (Fast Multi-Channel Photonics Alignment) Meander and Spiral Scans for efficient area-based signal acquisition and device characterization
- Multi-Axis Gradient Search for rapid signal optimization across multiple degrees of freedom
- PILightningFast First Light Search, an optional feature delivering first-light detection over a 500×500µm² area in just 0.3 seconds
These routines enable full-area spiral scans of 100×100µm² and 500×500µm² in as little as 0.3 seconds and 2 seconds, respectively. After first light detection, search gradient convergence occurs in just 0.3 seconds, supporting both coarse acquisition and fine optimization with unmatched efficiency.
