Adjustable spectacles torque test

Customised engineering example

Adlens manufacture adaptive spectacle lenses, where the optical power is adjusted by a side dial which is then removed. Among other tests, they needed to measure the running torque and rotation to destruction of the dials, to test for smooth running and consistency. An essential element in such low-torque testing is concentric alignment for detection of imperfections.

A Vortex-i torque tester with Emperor software was fitted with a custom fixture to support the lens piece, whilst a custom-moulded mandrel engaged the adjustment dial. The fixture pair enabled adjustment for accurate alignment, repeatable testing and detailed examination of the dial rotation quality.
