Abstract
A transparent optical component comprises two sets of cells (1) disposed in respective superposed layers (10, 20). Each cell (1) contains an optically active material, and the cells in each set are isolated from one another by separating portions (2) within the corresponding layer. The cells (1) of one layer are offset relative to the cells of the other layer so as to be located in line with the separating portions (2) pertaining to the other layer. Such optical component exhibits transparency that is improved compared with components having a single layer of cells or cells that are superposed.
