Key comparison on calibration of angle standards
Project Description
The key comparison on calibration of angle standards will be based on two 12-sided optical polygons. A first one manufactured by Matrix and a second one manufactured by Möller Wedel.
Due to the high number of participants, two groups of NMIs will be created:
A first group will measure only the polygon manufactured by Matrix, while a second group will measure only the polygon manufactured by Moeller Wedel.
