Technological advancements have led to incredible break throughs in the automotive industry, such as self-driving and environmentally compliant vehicles. Now, a new development from EDL Rethschulte, which specializes in lighting design, has the potential to change the view of and from the car through a novel micro-lens array (MLA) wafer technology, which allows for the production of extremely compact and light LED projectors the size of a thimble.

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.
