Motion Control
 Moving Beam Systems
U.S. Laser offers a line of overhead optics moving
beam systems. Essentially, the systems are precision X- Y tables which
are specially designed to be used on laser systems to accurately move
the beam over a fixed work piece. Standard systems have travel
distances of 6" X 6" , but larger systems are available on special
order. Drive motors may be either stepper or D.C. drive, and are
available with linear encoders. Other available options include motor
drives and control software, as well as coaxial CCTV systems. To
determine the system most appropriate for your needs, please contact
the U.S. Laser sales department.

High Speed
Galvanometer Beam Delivery
U.S. Laser offers a 2 axis beam delivery system
based on high speed galvanometer motors. The package includes
galvanometers, mirrors, flat field lens assembly, support structure, as
well as drivers and amplifiers. Each galvanometer is positional driven
by a customer supplied +/- 5 vdc signal. Custom drive software is
available. For scanning systems for use at wavelengths other than 1064
nm, contact sales department.

 X-Y Tables
These tables are used to accurately position and
move the work piece under a fixed laser beam. They are available in
either stepper motor or D.C. drive versions, and in sizes 4" x 4" and
larger. Typical stepper motor tables are programmable in .001"
increments, while more precise D.C. drive versions are available with
accuracies of 1 µm and better. U.S. Laser also offers motor drives and
computer programmable motion control software. Contact the U.S. Laser
sales department to discuss your needs.

Vertical
Axis Control
 For
elevating parts in a laser work chamber primarily intended for use with
a marking system. The Z-Axis part height stage incorporates a
stabilized scissor jack designed to provide the highest aspect ratio in
fully collapsed to fully extended travel. The height change
is implemented via stepper motor and drive electronics which are
interfaced to the system computer. The fully collapsed height
of the stage is approx 4.5 inches with a height adjustment of 4.5
inches for a fully raised height of 9 inches. The maximum pay load to
be lifted by the stage is 35 lbs. The standard stage is
available with a 12 inch x 12 inch top plate, with an option for 16
inch x 16 inch top plate.
 Workpiece Holding
Plates
U.S. Laser workplates are designed to securely
hold parts by mechanical clamping during laser processing operations.
Specifically designed for flat substrates, such as solar cells, silicon
wafers, and alumina plates, they can easily be adapted to other uses.
Various sizes and shapes are available to accommodate the wide rage of
substrate configurations. For vacuum hold-down fixtures, see the vacuum
chuck section of this catalog. Please contact our sales department to
discuss your work holding needs, perhaps we can help.

 Vacuum Chucks
U.S. Laser vacuum chucks are holding fixtures
which use the vacuum force, rather than mechanical clamping, to
maintain part positioning during laser processing. Many different
sizes, shapes and configurations are available. Specifically designed
for flat substrates, such as solar cells, silicon wafers, and alumina
plates, they can easily be adapted to other uses. Please contact our
sales department to discuss your work holding needs, perhaps we can
help.

 Rotary Chucks
Rotary chucks are used to rotate a circular part
under a fixed or moving laser beam. Rotating speed may be controlled by
either a variable speed control, or may be interfaced to an external
computer system for programmable speed control. Systems are available
with either D.C drive or stepper motors, and will accommodate parts
from 1 mm to > 35 mm diameter. These chucks are especially
popular for use with laser marking systems when it is desirable to mark
on the O.D. of a circular part. For further information, please contact
the U.S. Laser sales department.

 Wafer Handling
System
Wafer handling systems are used to automatically
load and unload silicon wafers for laser processing. Wafers up to 8"
diameter are cassette loaded into the machine. The system then
automatically picks up the wafer from the cassette and positions it on
the turntable. The wafer is then rotated and repositioned until it is
centered. Once the wafer is centered, the system can be programmed to
rotate the wafer to the desired orientation for laser processing. After
the processing is complete, the wafer is downloaded to the cassette,
and another wafer is retrieved until the entire cassette has been
processed. All necessary hardware and software are included with the
package.
