Dovetail holder for self-focusing and GRIN lenses used in compact fiber-coupling assemblies.
Datasheet (PDF) ↗Catalog context
APFP-GH is listed as APFP-GH GRIN-lens mount in the Fiber Alignment Accessories family. The local catalog record provides these first selection fields: Type: GRIN / self-focusing lens holder; Maximum optic diameter: <4.8 mm; Release: Side jackscrew.
| Type | GRIN / self-focusing lens holder |
|---|---|
| Maximum optic diameter | <4.8 mm |
| Release | Side 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-GH to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Maximum optic diameter: <4.8 mm. Check diameter and thickness together. A holder that accepts the diameter can still fail to retain an optic that is thinner than its minimum, and clear aperture is normally smaller than the optic the mount holds.
Model selection
Compare APFP-GH 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.
