Optical beam processing device

A light transmissive optical component comprising:

• an electroactive material layer structure comprising an optically active layer which implements an optical function;
• an electrode arrangement for controlling deformation of the electroactive material layer structure thereby to change a light transmission property of the light transmissive optical component;
• and
• a drive arrangement for controlling drive signals applied to the electrode arrangement,
• wherein the drive arrangement is adapted to induce different relative thickness changes at different regions of the electroactive material layer structure thereby providing non-uniform change in optical function between those different regions, and
• wherein at least some different regions of the electroactive material layer structure have different dielectric constant and/or stiffness.
