Each application benefits from higher speed, and higher accuracy control of the focal point, for saving time, increasing throughput and improving quality. The V-308 nanopositioning linear slide is designed for vertical loads up to 1kg, controlled by a voice coil linear motor and a frictionless counterbalance. The design combines high dynamics, nanometer resolution and reliable operation in high duty cycle applications.
