FiberGrate® is the world’s first complete turnkey motion
sub-system specifically designed for the manufacture of fiber
Bragg gratings. A flexible workspace allows the system to be optimized
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 solution that
requires no integration by the end-user. All components are designed
and manufactured by Aerotech’s motion control experts, ensuring
a turnkey, fully optimized 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 LZR series laser interferometers provide 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 fiber and mask to eliminate
Abbe error, resulting in exceptional accuracy. For less stringent
applications, two different noncontact linear encoders (2 nm or
10 nm resolution) 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 synchronized 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.
