optique

Thin-film optics is the branch of optics that focuses on thin, structured layers of different materials. These layers range from a fraction of a nanometer up to several micrometers thick but are usually in the order of the wavelengths of ultraviolet light, which is about 500nm. Their synthesis is controlled via deposition, with one or more layers of material layered onto the substrate, usually via physical vapor deposition.

Computers process information based on arrays of so-called bits. Each bit can take the values of one or zero. This is typically realized with integrated electronic circuits permanently written onto a semiconductor chip.
