Renishaw (Hoffman Estates, IL) has introduced the "lean design" XL-80 laser calibration system. The new design allows a 4X faster slew rate, 10X higher dynamic data capture rate, and total system accuracy in a smaller, lighter and more portable package. The XL-80 features linear measurement speed to 4m/s, while providing a resolution of 1nm. A new signal gain switch gives the option of 80m linear range or increased signal strength at shorter ranges. System accuracy of ±0.5 ppm is maintained over the full operating range of 0-40°C (32°-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. The XL-80 takes readings at 50 kHZ. The 10X increase in bandwidth enables capture of detailed data about small high-frequency movements.
