Micropositioning: PentaPod® & OctaPod™ Multi-Axis Systems
3SAE offers two flagship micropositioning platforms: the PentaPod® for high-stiffness precision motion and the OctaPod™ for autonomous photonic alignment. While the PentaPod® serves as the gold standard for sub-micron manual or programmed positioning, the OctaPod™ functions as a task-oriented microrobot with embedded intelligence to automate peak-power seeking, multi-channel I/O alignment, and drift tracking.
- PentaPod® Precision: Uses a patented parallel kinematic design to deliver 6 Degrees of Freedom with zero crosstalk.
- OctaPod™ Automation: Features an integrated dither module for real-time multichannel optimization for production test and assembly applications in Silicon Photonics (SiPh).
- Industrial Build: Both systems feature a 20,000-hour MTBF and 20-minute field-serviceable actuator replacement.
Precision alignment is the foundation of optical performance. When you're working with devices that require sub-micron accuracy, you don't just need a stage that moves; you need a system that thinks. These micropositioning solutions range from ultra-stable positioners to fully autonomous microrobots. The PentaPod® Multi-Axis Positioner provides the structural rigidity of a mountain, while the new OctaPod™ acts more like a skilled technician, finding the best coupling and staying there automatically. Integrating these tools into your test and assembly processes ensures your production throughput and yield are world-class.
Choosing Your System: Positioner vs. Microrobot
The choice between a PentaPod® and an OctaPod™ depends on whether your process requires a device you command to move or a device you command to accomplish a task.
The PentaPod®: The Gold Standard for Motion
The PentaPod® is designed for applications where absolute positional stiffness and accuracy are paramount. Its singularity-free design means you won't encounter "dead zones" in the middle of a critical movement.
- Singularity-Free: True parallel kinematics ensure smooth motion across the entire workspace.
- High Stiffness: Minimal crosstalk ensures that movement in one axis doesn't disturb others.
- Compact Footprint: Integrated controllers mean no bulky external electronics racks.
The OctaPod™: The World's Most Productive and Robust Photonic Alignment Microrobot
The OctaPod™ is engineered specifically for the SiPh "Planar Photonics" era, where alignment is often the primary production bottleneck. It moves intelligence from the host PC directly into the hardware.
- Real-Time Tracking: An integrated dither module uses spiraling circular motion to rapidly achieve and optionally track peak power, automatically compensating for thermal and curing stresses.
- Autonomous Tasks: Uses "Do This" commands to perform scan-and-return-to-optimum tasks without software lag.
- Multichannel Optimization: Rapidly aligns fiber arrays to complex photonic integrated circuits (PICs).

Built for Production Economics
The industry has moved away from "lab-grade" tools that fail under the pressure of 24/7 manufacturing. Whether you choose the PentaPod® or the OctaPod™, you're investing in a platform built for the fab.
Programming and integration are easy, for rapid deployment. Both systems are platform-agnostic, using tidy, mnemonic command sets that integrate easily into your existing MES via Python, LabVIEW, or C++. Because the electronics are embedded, you won't have to deal with a "rats-nest" of cabling or bulky external cabinets that take up valuable floor space.
Total Alignment Control
The microrobot alone would be nice as-is, but 3SAE takes it one step further with the entire ecosystem.
- Prepare: Ensure pristine end-faces with precision fiber cleavers.
- Align: Execute sub-micron optimization with the OctaPod™ or PentaPod®.
- Validate: Verify documented performance with NorthLab ProView™ interferometers.
- Integrate: Complete the assembly with specialty fusion splicing.
