Squareness error calibration of a CMM for quality control of ophthalmic lenses Quiroga Mellado, Juan Antonio Rodríguez Ibáñez, Diego Alonso Fernández, José 535 CMM Calibration Squareness Error Volumetric Error Ophthalmic Lenses Quality Control Óptica (Física) 2209.19 Óptica Física © The Author(s) 2013.

This paper proposes a calibration procedure for the squareness error of small-sized coordinate measuring machines like those used for ophthalmic lenses quality control. The proposed procedure only requires a spherical lens as a reference surface and it only needs to be measured once making this calibration method faster and cheaper than the existing ones.
