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.
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.
