Laser Calibration System

Renishaw’s XL-80 laser calibration system brings precision and portability to manufacturing machinery process validation, the company says. The system’s design allows for a 4× slew rate and a 10× dynamic data capture rate in a small, light and portable package. The system increases linear measurement speed to 4 m/s, while providing a resolution of 1 nm, even at top speed.

Renishaw’s XL-80 laser calibration system brings precision and portability to manufacturing machinery process validation, the company says.

The system’s design allows for a 4× slew rate and a 10× dynamic data capture rate in a small, light and portable package. The system increases linear measurement speed to 4 m/s, while providing a resolution of 1 nm, even at top speed.

The system brings nanometer-level motion analysis to calibration, error-mapping and compensation of everything from laboratory equipment, semiconductor processing machinery and radiosurgery tools to CMMs, lithography equipment, advanced machine tools, robots and assembly systems. A new signal gain switch gives the option of 80-m linear range or increased signal strength at shorter ranges.

This system is backwards compatible with optics from the company’s ML10 laser series, enabling users of that system to upgrade while retaining their investment in optics, procedures and staff training. A full range of optics enables highest precision interferometer determination of a machine’s linear, angular, flatness, straightness and squareness measurements to international checking standards.

System accuracy is ±0.5 ppm and is maintained over the operating range of 0 to 40oC.

The XL-80 laser unit weighs more than 3 kg including connecting cables, power supply and sensors. The reduced dimensions of the laser head and stage allow for easy mounting on an available magnetic base where tripod mounting is inconvenient.
