Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Fine-pitch screws convert a comfortable knob rotation into a few microns of travel.
Raise the resolution of a mount already in service by changing only its adjusters.
Radial locking holds the setting once alignment is complete, through handling and thermal cycling.
System integration
Use these checks to connect ACFS25-1 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Adjustment Screw Thread: M6x0.25. 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.
Screw Pitch(mm): 0.25. 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 ACFS25-1 with the closest available models in the ACFS series Adjustment Screw 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.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
