Vision for success in QC

A Mecmesin Vortex-i torque tester is helping an optics company deliver vision to sight-challenged people in the developing world. Adlens makes adjustable lenses and has an innovation centre in Oxford. Its liquid-filled lenses let the wearer selfadjust magnification of their spectacles manually. Lenses are adjusted by thumb-and-finger rotatable dials on the frame and are detachable once the correct magnification has been selected.

A Mecmesin Vortex-i computercontrolled torque tester is used to ascertain that rotating components of the lenses are reliable and easy to use.

A sample lens, with dial attached is fitted to a special fixture on the Vortex-i. The Vortex-i is preprogrammed to perform 10 or 1.5 rotations, 1.5. for end-of-line checks, and 10 for destructive verification testing. The graphical representation, provided by the systems software, Emperor, means easy identification of anomalies in the dials movement.
