Abstract: An optically effective element includes a carrier, a first optically effective structure arranged on a top side of the carrier, and a cover arranged above the first optically effective structure. A method of producing an optically effective element includes providing a carrier, forming a first optically effective structure on a top side of the carrier, and arranging a cover above the top side of the carrier and the first optically effective structure.
