Abstract:
There is provided a lens element configured so that optical characteristics thereof remain substantially stable over a range of operating temperatures. In one embodiment, a fluid lens element can be provided that includes a membrane having a formation formed thereon for accommodating changes in characteristics of the lens element attributable to changes in temperature so that an amount of perturbations in the lens element which would otherwise be exhibited with thermal expansion of the membrane are minimized.
