OPTICAL HEAD WITH A VARIABLE OPTICAL COMPONENT

摘要

An optical head (10) using a variable optical component (10), which component co mprises bendable nano-elements (3) that can be switched between a bent and non-b ent state by means of a driver-field applied between electrodes (1, 2). In the b ent state the nano-elements absorb radiation and therefore adapt the radiation i ntensity distribution of the radiation beam passing the component.
