Abstract

There is presented an optical element 100, such as a tuneable lens, wherein there is provided means 128 to mitigate problems with stress concentration in a bendable cover member 102 at a border of a supporting structure 101, which in the absence of said means would entail a stress singularity issue due to an abrupt change in mechanical properties around the bendable cover member 102.
