6 axes · integrated controller
Multi-axis positioner for photonic alignment
PentaPod is a parallel-kinematic positioner with six degrees of freedom (XYZ and three rotations). The controller is built into the housing, eliminating the need for a separate control cabinet. The PPD-01-0130 version also provides Ethernet with PoE and two analog measurement inputs. Designed for silicon photonics testing and assembly, it is suitable for both laboratory and production environments.
Three linear axes (X, Y, Z) and three rotations (θX, θY, θZ). The virtual pivot point is software-configurable over a range of up to 8 m in X, Y and Z.
Linear motion along X
Values from the 3SAE datasheet. Centered load capacity: up to 2 kg; stiffness: 24 N/µm.
PentaPod is a photonic alignment microrobot, rather than a conventional stack of stages or a hexapod. According to 3SAE, its patented parallel-kinematic design eliminates the 24 rotary bearing sets of traditional Stewart-platform hexapods, delivering high stiffness, short settling times and low crosstalk between axes.
The technology was developed in 2016 and integrated into the PentaPod Fusion Splicer in 2019. It has been used in high-volume manufacturing for years.
Built-in scanning and optimization routines support multiple channels, with simultaneous input and output optimization. Alignment can be configured for different optical-axis orientations, including grating and edge couplers. Real-time tracking supports compensation for thermal stress and curing shrinkage.
The integrated fanless controller saves rack space. A USB-C or Ethernet connection simplifies integration and reduces the moving cable bundle around the stage.
No fans or sweeping cables around the stage. Its 197 cm² footprint saves valuable production space. Platform-independent ASCII commands simplify programming and integration.
The stepper-drive design does not require servo tuning. 3SAE describes the design as eliminating servo oscillation and runaway; Intelligent Initialization™ is designed to prevent hazardous motion of long fixtures.
PentaPod stages are also used in the 3SAE PFS.

PPD-01-0125
Carriage platform with an M3 threaded hole grid, control software, USB Type A/C cable, power supply, electronic user manual and a one-year manufacturer's warranty covering parts and labor.
PPD-01-0130
Includes the above, plus integrated Ethernet with PoE and two analog input channels.

Both designs provide six axes and a virtual pivot point. The comparison below summarizes 3SAE's claims; hexapod features vary by model and configuration.
| Feature | PentaPod® | Hexapods (Stewart platform) |
|---|---|---|
| Scanning and alignment | built in | varies by model |
| Controller | integrated | often separate; varies by model |
| Cabling | single USB-C or Ethernet connection | depends on the model and controller |
| Fan | none | depends on the controller model |
| Tuning | not required | on application or load changes |
| Oscillation and runaway | eliminated by design, according to 3SAE | depends on the drive and control system |
| Field serviceability | yes | generally not |
| MTBF | > 20,000 h | rarely specified |
| Inverted mounting | yes | yes (some models) |

It is an industrial photonic alignment microrobot, rather than a conventional stack of stages or a hexapod. It is compact, designed for cleanroom use and includes built-in alignment routines.
The technology was developed in 2016 and integrated into the PentaPod Fusion Splicer in 2019. According to 3SAE, it is used in high-volume manufacturing worldwide.
PentaPod can be used in workstations with 3SAE equipment. Fixture selection, interfaces and configuration depend on the application. Compatibility with a particular splicer or fiber preparation system must be confirmed before ordering.
Approximately 20 minutes. Return to the manufacturer is usually unnecessary; most repairs can be carried out on site.
Yes. 3SAE's engineering team develops integration solutions for OEMs and research institutions. We can help communicate your workstation requirements and select the appropriate version.
