Physical optics - Physical optics, or wave optics, is used in physics to refer to the branch of optics which studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid. This usage tends not to include effects such as quantum noise in optical communication.

Thin-film optics - Thin-film optics is the branch of optics which deals with very thin structured layers of different materials. In order to exhibit thin-film optics, the thickness of the layers of material must be on the order of the wavelengths of visible light (about 500 nm).

Non-imaging optics - Non-imaging optics is the branch of optics concerned with the optimal transfer of light between a source and a target. Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the source; instead the maximal illumination of the target by the light from the source is desired.

Optics - Optics (appearance or look in ancient Greek) is a branch of physics that describes the behavior and properties of light and the interaction of light with matter. Optics explains and is illuminated by optical phenomena.
