Renishaw Unveils XC100 Environmental Compensator, Targeting 0.4 ppm Laser Calibration Accuracy

Renishaw has announced the launch of its new XC100 environmental compensator, set to debut at IMTS 2026 and AMB 2026. The system builds on Renishaw's proven XC-80 technology and delivers real-time automatic wavelength correction with an improved 0.4 ppm linear laser measurement accuracy.

Closing the environmental variable

Laser calibration is only as trustworthy as the conditions in which it's performed. Air temperature, air pressure, and relative humidity all influence measured laser wavelength, and the XC100 addresses each: it measures all three parameters and automatically adjusts the measured wavelength in real time. It also measures material temperature, which enables calibration results from machines operating at different temperatures to be normalised to a standard temperature — a practical answer to a persistent source of inconsistency when comparing results across machines or sessions.

Designed to fit existing workflows

Compatibility matters here. The XC100 works with the XL-80 laser interferometer, the XM-60 and XM-600 multi-axis calibrators, and CARTO software, so it slots into Renishaw's existing calibration product range rather than demanding a new one.

Flexibility extends to hardware configuration. The system supports any combination of air and material sensors, allowing comprehensive measurement of environmental conditions throughout the machine volume. A high-resolution LCD touchscreen display, flexible sensor configuration, and versatile mounting options round out a package designed to adapt to a range of calibration applications rather than the other way around.

"The XC100 simplifies the process of precision laser calibration. By combining real-time environmental monitoring with seamless CARTO software integration, users can be confident in their measurement results, even in changing conditions."

Where to see it

The XC100 will be showcased at IMTS 2026 in Chicago, USA, from 14 to 19 September, and at AMB 2026 in Stuttgart, Germany, from 15 to 19 September. For calibration engineers weighing whether improved environmental compensation justifies an upgrade from XC-80-based setups, the 0.4 ppm figure and the live demonstrations at both shows should provide a concrete basis for evaluation.
