Laser Interferometer Position Measurement Systems

Keysight Technologies

When built into manufacturing and inspection equipment, a laser interferometer system reports the position or controls the motion of a product platform with more accuracy than any other method. It allows manufacturers to produce precision products from integrated circuits to medical devices to aerospace components that meet the most stringent specifications.

Beam Directing and Reflecting Optics

Keysight Technologies

Beam directing and reflecting optics simply reflect, bend or translate the beam, but do not typically modify the polarization, except for polarizing beam splitters. For example, mirrors, cube corners and retroreflectors are attached to objects that move in order to keep the weight down on the moving object (instead of mounting the interferometer on the moving object).

2-Axis High-Resolution Laser Axis Board for VME

10898D - Keysight Technologies

The 10898D 2-axis high-resolution laser axis board provides the same resolution as the Keysight 10897D high-resolution laser axis board with increased slew rates and reduced noise. The increased stage velocity limits and low noise compared to previous laser systems offer premium positioning repeatability and accuracy for advanced applications such as IC fabrication equipment.

Laser Heads

Keysight Technologies

The laser head is the source of the laser beam used in all laser motion and position measurement systems. The primary difference between laser heads is in the velocity, reference frequency and optical output power. Other considerations are size, heat dissipation, and input power requirements. Which laser you choose depends primarily on the application in which it will be used. For example, semiconductor lithography systems typically have faster moving parts (stages), and therefore need higher velocities than machine tool applications.
