Abstract

There is presented a transparent optical device element (700) comprising an optical lens (744), comprising one or more piezoelectric actuators (206, 208, 210), wherein said optical lens (744) comprises an optical aperture (632), and wherein the optical device element furthermore comprises a passivation layer (312, 314, 742, 628) placed on said optical lens, said passivation layer comprising a barrier layer (312) forming a humidity barrier, and being located on at least a portion of said cover member, where said portion of said cover member is intersected by the optical axis, and on said piezoelectric actuators, and wherein the passivation layer furthermore comprises one or more further layers (628) located on at least said portion of said cover member being intersected by the optical axis, wherein said passivation layer forms an anti-reflection coating for said optical lens (744) at least along the optical axis (634).
