WebAlthough much thinner than conventional optical interference coatings, nanometer-thick films made of optically absorbing materials can display strong interference effects. This … WebAccording to optics, a thin film refers to a thin layer of a material having the thickness in the range of sub- nanometer to micron s. When light waves fall on the thin film surface then the waves are either reflected back from the upper surface of the material or are transmitted through it. The light waves that manage to get transmitted ...

WebSummary. Thin film interference occurs when light reflects multiple times off the two sides of a thin transparent material. Thicknesses on the order of 0.1 μm~10 μm ( ¼λ~10λ of visible light within the film) are considered "thin". Thin film interference can be both constructive and destructive.
