TRANSPARENT OPTICAL ELEMENT INCLUDING A CELL ASSEMBLY

摘要

The invention relates to a transparent optical element (100) including an assembly of cells (1) having variable respective depths (h) as measured in a direction (N) perpendicular to a surface (S1) of the element having said cells. The cells can be filled with a gas or with mixtures of at least two components having different light refraction index values. The variation of the cell depth increases the variation of an equivalent value of the light refraction index associated with each cell, and reduces the roughness of a lens equivalent to the optical element.
