Abstract

An optical component (10) comprises a transparent set of cells (15; 25) juxtaposed in parallel to a surface of the component. Each cell is hermetically sealed and contains a substance with an optical property. The set of cells comprises cells of several sizes. The size of the cells can be varied between various locations of the surface of the component (10), for making it possible to cut out the component without altering its optical properties. Furthermore, the variation in size of the cells serves to prevent diffraction or scattering from being visible in certain zones of the component.
