PI (Physik Instrumente) L.P. has added two models to its PInano superresolution microscope stage series. The new stages’ direct-measuring capacitive sensors provide higher linearity and longer-term stability than do piezoresistive sensor-equipped stages. They also are less sensitive to noise because of a high-frequency measurement principle, as opposed to the DC-based sensing technique used in piezoresistive sensors. The large aperture accommodates microscopy accessories such as slide and petri dish holders. The recessed bottom slide mount allows full rotation of the turret without in-and-out Z-motion, protecting objectives from crashing into the stage on turret rotation. X-Y and X-Y-Z stages are available. The low-profile 20-mm design facilitates integration into inverted microscopes from Leica, Nikon, Olympus and Zeiss.
