Mountable in a horizontal or vertical axis, the VCS-2020 cross-roller voice coil stage features sub-micron, >300 nm positioning resolution and a 20 mm diameter aperture. An integrated analog position-feedback sensor ensures 100 nm repeatability, and includes a voice coil actuator, analog position sensor, servo amplifier, and servo controller. The low inertia cross-roller stage is integral to the standard threaded “C” lens mount and motor coil for tip/tilt-free motion. Custom lens mounts are also available.

PRESS RELEASE
High Speed, High Force, Sub-micron Positioning, Voice Coil Stage Features 20 mm Aperture
Sunnyvale, CA, — High speed, high force, sub-micron, >300 nanometer (1.1811 10-6 in.) positioning resolution, cross roller voice coil stages are self contained, compact, and can be mounted in a horizontal or vertical axis. The high speed, 20 mm (0.7874 in.) travel, Equipment Solutions’ VCS-2020 Voice Coil Stage features a 20 mm dia. aperture. An integrated Analog position feedback sensor assures 100 nanometer (3.937 10-6 in.) repeatability. This compact voice coil stage is ideal for such micro-positioning applications as: Scanning interferometry, disk drive testing, auto focus systems, surface structure analysis, confocal microscopy, biotechnology, and semiconductor test equipment.
The compact 117 mm 75 mm 81 mm (4.60 in. 2.96 in. 3.18 in.), low mass, voice coil stage is a fully self-contained system including a high precision cross roller stage, voice coil actuator, analog position sensor, servo amplifier and servo controller. The low inertia cross roller stage is integral to the standard threaded "C" lens mount and motor coil for tip/tilt free motion. Custom lens mounts are available. The voice coil motor is rated at 17.8 N (4 lbs.) continuous force and 71.8 N (16 lbs.) peak for 10 seconds and is clean room compatible. For easy integration into a new or existing application the VCS-10H Voice Coil Stage has multiple sets of mounting holes on several surfaces.
