Renishaw Intros Compact Laser Calibrator
Laser calibration system.
Hoffman Estates, IL — Renishaw's new lean-design XL-80 laser calibration system brings greater performance, precision, and portability to manufacturing machinery process validation. The new laser interferometer calibration system is a "lean design" system that reportedly allows a 4X faster slew rate, 10X higher dynamic data capture rate, and best total system accuracy in a smaller, lighter and more portable package.

Meeting industry trends to high-speed machinery, higher precision and greater process control, the XL-80 increases linear measurement speed to 4m/s, while providing a resolution stated at 1nm, even at top speed. Lightweight, compact packaging enables easier transport and setup, with fast warmup of less than six minutes to minimize waiting time.

The XL-80 brings nanometer-level motion analysis to calibration, error-mapping and compensation of everything from laboratory equipment, semiconductor processing machinery and radiosurgery tools to coordinate measuring machines, lithography equipment, advanced machine tools, robots, and assembly systems. A new signal gain switch gives the option of 80m linear range (such as for large aircraft profilers) or increased signal strength at shorter ranges. The new instrument is backward-compatible with optics from the company's ML10 laser system, enabling thousands of current ML10 users to upgrade to the new system 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 of ±0.5 ppm is maintained over the full operating range of 0 to 40°C (32 to 104°F). A new XC-80 Intelligent Sensor System maintains that accuracy against variations in temperature, pressure and humidity by updating the environment factor every seven seconds via a USB link. As with the ML10, all measurements are based on the wavelength of a stabilized HeNe laser source, giving users assured traceability back to internationally recognized length standards.

The XL-80 takes readings at 50kHZ, up from 5kHZ. The 10X increase in bandwidth enables capture of detailed data about small high frequency movements. Enhanced versions of Renishaw software (LaserXL and QuickviewXL) present data in easy-to-use style. Faster warm-up gives highest measurement productivity. This is especially important for calibration service providers and large manufacturing organizations needing to perform measurements on multiple machines, particularly on regularly scheduled predictive/preventive maintenance programs. A new multi-signal connector facility increases XL-80 flexibility. It provides a standard trigger signal-in (for data capture), an analog voltage-out facility, and an optional quadrature signal output. Connection to a PC is now via USB, so no separate interface is required.
