Motorised stage speeds into position

An Orlin Technologies product story
Edited by the Engineeringtalk editorial team Apr 18, 2006

Available now from Orlin Technologies is the fastest motorised microscope x-y stage currently available.

Available now from Orlin Technologies is the fastest motorised microscope x-y stage currently available.

With move and settle time of less than 100ms over the entire 15mm travel range, the LXYM15 open-frame x-y stage from SMAC is ideal for scanning applications as diverse as live cell imaging and semiconductor inspection.

Motive force comes from direct-drive, noncogging voice coil linear motors with closed-loop servo control, whose unique design reduces moving mass and maximises dynamic performance.

Without rotary to linear conversion devices (such as leadscrews) to introduce friction and backlash, this speed is not however at the expense of precision.

Noncontact optical linear encoders for position feedback are fitted as standard with resolution options between 5 and 0.5um (100nm version in development) and repeatability as low as +/-0.5um.

Acceleration, velocity and position are all fully programmable when combined with SMAC's LAC-25 high speed servo controller.

The LAC-25 also has analogue and digital inputs and outputs for interfacing to other systems.

The LXYM15 features precision guiding systems strategically positioned relative to the stage insert to ensure flatness across the system.

The current model is compatible with the Zeiss microscopes but standard models for other manufacturer's microscopes are in development.

Custom mounting features and inserts can be configured to suit the user's application if required.
