The baseline design of the European Extremely Large Telescope features a telescope with a 39-meter-class primary mirror (M1), consisting of 798 hexagonal segments. A measurement machine design is presented based on a non-contact single-point scanning technique, capable of measuring the form error of each segment with nanometer uncertainty, fast, and with low operational costs. The implementation of a tactile precision probe eliminates the need for the CMM in the earlier segment manufacturing process. Preliminary assessment show nanometer-level uncertainty after calibration.
