Target positioning system used in laser research facility

Application

Positioning of ‘micron scale’ Laser Targets within Vacuum Vessel

Scope of overall contract.
Supply of 4-Axis IN-VAC (Clean Room Prepared ) Laser target positioning-stage assembly package with local piezo servo motor drive control and encoder interface enclosure. Plus 4-axis sub-micron accuracy motion control system with embedded co-ordinate correction algorithm and ethernet PC interface.

Description of equipment and services supplied.
In Laser Research applications it is necessary to have the ability to manipulate a very small target sample in three dimensions in order to direct the Laser power at precise locations on the target sample. This can be achieved by initially acquiring a metrology image of the target using a laboratory based Vision System with high levels of Zoom and magnification.The acquired 3-D co-ordinates are then replicated on an identical positioning system within the Vacuum target chamber for target processing. Micromech Systems Ltd specified and pre-tested the Target-Positioning 4-axis motion stage assembly for carrying out this process. The Target Metrology System (TMS) with vision workstation was also supplied under a separate contract for this client.
