APFP-OM objective-lens mount
Dovetail objective mount for positioning microscope objectives in fiber-coupling and photonic-device assemblies.
Datasheet (PDF) ↗Catalog context
APFP-OM is listed as APFP-OM objective-lens mount in the Fiber Alignment Accessories family. The local catalog record provides these first selection fields: Type: Objective-lens mount; Objective thread: WJ 4/5-1/36″; Base: APFP dovetail.
| Type | Objective-lens mount |

| Base | APFP dovetail |
| Compatibility | UFP, NFP, and APFP stages |
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-OM 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.
