Zeiss’s Xenos coordinate measuring machine (CMM) will be used by the National Institute of Standards and Technology (NIST) at their Physical Measurement Laboratory (PML). This is to help scientists make a measurement of big G, the universal constant of gravitation that has eluded precise measurement for centuries, the company says.

The big G experiment will start this spring and should be complete within two years. When that experiment is complete, however, the researchers hope to incorporate the instrument into their growing fleet of CMMs, capable of making some of the most precise dimensional measurements in the world.

According to the company, the Xenos measuring system features a length measurement error of just 0.3 micrometers. It also has a probe head that can move in all three dimensions.
