FiberGrate® is a high precision, high-performance motion sub-system specifically designed for the manufacture of fibre Bragg gratings. A flexible workspace allows the system to be optimised for the unique needs of each manufacturer.
FiberGrate represents a major evolution as only Aerotech has the breadth of product line to offer a single-source motion solution that requires no integration by the end-user. All components are designed and manufactured by Aerotech's motion control experts, ensuring a fully optimised solution.
Linear Stage
The linear positioner is based on Aerotech's ABL2000 series linear air bearing, and is a fully preloaded, noncontact design. Inherently frictionless, air bearings have proven to be the standard in precision applications. Driven by a noncontact linear brushless servomotor, this stage proves the ultimate solution whether the application requires small, accurate steps or constant smooth velocity. Years of research have resulted in a robust and perturbation-free cable management system. High-flex ribbon cable ensures years of maintenance-free operation.
Feedback and Control System
Aerotech's optional laser interferometer feedback provides high stability, high resolution (0.3 nm) feedback. Designed for use with Aerotech's Automation 3200 series controller, the interface between the interferometer and control systems is seamless. The laser is positioned at the height of the fibre and mask to eliminate Abbe error, resulting in exceptional accuracy. For less stringent applications, two different noncontact linear encoders are offered. A wide selection of state-of-the-art controllers are available. Options range from single-axis, stand-alone controllers to the Automation 3200 software-only controller capable of 32 axes of synchronized control. All of Aerotech's controllers offer position synchronised output pulses to control the laser. In addition, real-time position information may be logged on-board the controller, or read over high-speed parallel or serial interfaces.
Options
The FiberGrate may be configured with standard or custom granite, as well as vibration isolation systems. Additional indexing axes are available and are readily interfaced with the control and drive system. Convenient rack- or panelmount amplifiers are included with all systems. All systems have provisions for customer cabling.
Aerotech's expert technical staff is experienced in custom system designs and will work with you to generate a system to meet the unique needs of your application.

- Available with Aerotech controllers.
- Requires environmental compensation.
- Maximum speed based on stage capability; maximum application velocity may be limited by system data rate and system resolution.
- Maximum load based on bearing capability; maximum application load may be limited by acceleration requirements.
- To protect air bearing against under-pressure, an in-line pressure switch tied to the motion controller/amplifier ESTOP input is recommended.
- Air supply must be clean, dry to 0°F dew point and filtered to 0.25 µm or better; recommend nitrogen at 99.9% purity.
- Specifications are for single-axis systems measured 25 mm above the tabletop. Performance of multi-axis systems is payload and workpoint dependent. Consult factory for multi-axis or non-standard applications.
- When mounting the ABL2000 in an XY configuration the maximum upper axis length is 300 mm.
