APFP-FH bare-fiber holder
Magnetic clamp for holding 125 µm bare single-mode fiber on APFP-compatible dovetail stages.
Datasheet (PDF) ↗Catalog context
APFP-FH is listed as APFP-FH bare-fiber holder in the Fiber Alignment Accessories family. The local catalog record provides these first selection fields: Type: Bare-fiber holder; Nominal fiber diameter: 125 µm; Clamp: Magnetic, side-release.
| Type | Bare-fiber holder |
|---|---|
| Nominal fiber diameter | 125 µm |
| Clamp | Magnetic, side-release |
| Base | APFP dovetail |
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.
Model selection
Compare APFP-FH with the closest available models in the Fiber Alignment Accessories 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.
