FIELD: process engineering.
SUBSTANCE: proposed process comprises preparation of substrate and its pre-structuring to make bulges on its face and recesses on its rear that comply with said bulges. Said substrate pre-structuring is performed by embossing via intaglio to apply translucent polymer in the area of bulges or recesses to make micro lenses on at least one side of said substrate. Production of substrate provided with micro lenses involves rigid connection of micro lenses with said substrate which features mirror symmetry relative to mirror plane aligned with mid plane of biconvex micro lenses and parallel with said substrate.
EFFECT: simplified process.
