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. Motorized, with stepper motors, will handle parts up to 45 pounds in weight. The fully collapsed height of the stage is 4.75 inches including the base and surface mounting plates. The stage will raise 4.75 inches for a total height of 9.5 inches. Available with a top plate of 16 inch by 16 inch. Programmable, compatible with US Laser’s marking and Friendly Motion systems, or through a software module which is provided, which allows computer control of absolute positioning or jogging with .001 inch resolution. Package includes the stage with motor, and the controller with RS232 interface.
Size: 18.5 inch X 16 inch X 4.75 to 9.5 inch, with 16 inch X 16 inch top plate or 4.25 inch to 9 inches without the top plate. Input power is 115/220 VAC.


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.
