Usually slow, so that only drifts are compensated. Only recently, high bandwidth (100Hz) have been reported with the use of voice coil actuators (Kelly et al. 2022; Geraldes et al. 2023). ### Degrees of Freedom {#degrees-of-freedom} - Full rotation for tomography: - Spindle bellow YZ stage: (Wang et al. 2012; Schroer et al. 2017; Schropp et al. 2020; Geraldes et al. 2023) - Spindle above YZ stage: (Stankevic et al. 2017; Holler et al. 2017, 2018; Villar et al. 2018; Engblom and others 2018; Nazaretski et al. 2022; Xu et al. 2023) - Only for mapping: (Nazaretski et al. 2015; Kelly et al. 2022) **Stroke**: - > 1mm: (Nazaretski et al. 2015; Kelly et al. 2022; Geraldes et al. 2023) ### Payload capabilities {#payload-capabilities} - Micron scale samples - Samples up to 500g (Nazaretski et al. 2022; Kelly et al. 2022) ### Nano Positioning End-Station without online metrology {#nano-positioning-end-station-without-online-metrology} {{< figure src="/ox-hugo/endstation_id11.png" >}} ### End-Station with integrated online metrology {#end-station-with-integrated-online-metrology}
