APFP-UM universal mounting module
Universal dovetail module with threaded mounting points for adapting custom optics and fixtures to fiber stages.
Datasheet (PDF) ↗Catalog context
APFP-UM is listed as APFP-UM universal mounting module in the Fiber Alignment Accessories family. The local catalog record provides these first selection fields: Type: Universal mounting module; Threaded holes: M3 and M4; Release: Jackscrew.
| Type | Universal mounting module |
|---|---|
| Threaded holes | M3 and M4 |
| Release | Jackscrew |
| 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.
System integration
Use these checks to connect APFP-UM to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Threaded holes: M3 and M4. Match the thread standard and hole pitch before ordering. Metric and imperial hardware interchange only through an adapter, and a thread that is nominally similar is not necessarily the same pitch.
Model selection
Compare APFP-UM 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.

PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.
