Abstract
A transferrable thin-film optical device and a head-mounted display are provided. A transferrable thin-film optical device comprises a thin-film layer providing at least one predetermined optical function. The thin-film layer is configured to be removably attached to a substrate, such that a molecular pattern for the at least one predetermined optical function of the thin-film layer is preserved post removal.

A transferrable thin-film optical device, comprising:
- a thin-film layer providing at least one predetermined optical function,
- wherein the thin-film layer is configured to be removably attached to a substrate, such that a molecular pattern for the at least one predetermined optical function of the thin-film layer is preserved post removal.
A head-mounted display (HMD), comprising:
- a thin-film optical device that is optically coupled to the HMD and is attached to a surface of the HMD after being detached from a substrate, the thin-film optical device providing at least one predetermined optical function and comprising:
- a thin-film layer providing the at least one predetermined optical function and configured to removably attach to the substrate, such that a molecular pattern for the at least one predetermined optical function of the thin-film layer is preserved post removal.
