Glossary Details

There are multiple contexts with nanopositioning where this term applies. Measurement bandwidth describes the frequency range over which a specification was acquired (this can a low pass filter cutoff frequency). For example, if a stage has 1 nm resolution, that is only half the story. Whereas describing 1 nm resolution over a 1 kHz bandwidth (for example) is a more useful description.

The bandwidth associated with response is slightly different, though certainly coupled to the above concept. A stage can only respond so quickly. If it is driven at  a frequency that is higher than its response bandwidth, the amplitude of the motion will be attenuated.
