Applications
Set-and-forget alignment
Adjust once during setup and lock, on axes that do not need to move again during the run.
Coarse positioning ahead of fine stages
Establish the optical axis by hand before a piezo or motorised stage takes the fine motion.
Prototyping and teaching rigs
Reconfigure a layout quickly, with no cabling, controllers or electrical noise added to the experiment.
