Fast Focusing Linear Slide has Nanometer Precision, High Dynamics, and Maintenance-free Voice Coil Motor

PI extends its large offering of nanometer precise, fast focusing stages with the addition of its new V-308 nanopositioning slide for vertical applications providing 7mm of Z-travel and 10nm incremental motion – ideal for OEM and research applications in the life science, semiconductor, and material science fields. The novel design combines long travel with unmatched dynamics and precision with 8m/s2 acceleration and 25nm bidirectional repeatability.

Closed-Loop Linear Slide Design with Voice-Coil Motor

The closed-loop linear slide uses an optical position sensor with sub nanometer resolution and a voice coil linear motor to allow vertical (or horizontal) travel up to 7mm with a velocity up to 200mm/sec (8”/sec) for fast accurate scanning. Guided by low friction cross-roller bearings, this low-profile linear slide delivers long lasting performance in high duty cycle industrial applications. Ease-of-use is built in with a user-adjustable counterbalance, (e.g. for heavy, large NA microscope objective lenses up to 1kg in vertical applications) and hard stop adjustability to limit the travel range.
