APFP-YZ standard-precision fiber alignment stage
Modular dovetail fiber-alignment stage for building compact translation and angular coupling assemblies with a consistent optical centre height.
Datasheet (PDF) ↗Catalog context
APFP-YZ is listed as APFP-YZ standard-precision fiber alignment stage in the Fiber Alignment Stages family. The local catalog record provides these first selection fields: Axes: Y / Z; Y travel: 12 mm; Z travel: 6 mm.
| Axes | Y / Z |
|---|---|
| Y travel | 12 mm |
| Z travel | 6 mm |
| Sensitivity | <2 µm |
| Drive orientation | Standard |
| Accessory interface | APFP dovetail ecosystem |
Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Adjust once during setup and lock, on axes that do not need to move again during the run.
Establish the optical axis by hand before a piezo or motorised stage takes the fine motion.
Reconfigure a layout quickly, with no cabling, controllers or electrical noise added to the experiment.
System integration
Use these checks to connect APFP-YZ to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Y travel: 12 mm · Z travel: 6 mm. Adjuster pitch sets the sensitivity you can actually work at. Confirm whether the stated figure is a total range or a per-revolution increment, and whether the mechanism is locked after adjustment.
Model selection
Compare APFP-YZ with the closest available models in the Fiber Alignment Stages family. Confirm option-dependent values on the final configuration before ordering.

Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
PhotonicsSingle-mode fiber does not preserve polarization. Pin the state, erase it with a scrambler, or maintain it in PM fiber — which one your measurement needs, and the response time and extinction ratio that decide it.
