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.
