[OPTIC] – What are Optical Thin Films? 10 août 2019

Thin films are thin coating layers present in many different technologies. Despite their widespread use, most of the focus is around how they provide a barrier to various stimuli, or how they can be used as a conductive medium. However, there is another class of thin films that we will discuss, and these are optical thin films.

[Thin Films] – A History of Thin Films in Optics 25 octobre 2020

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.
