Microoptics focuses on manipulating light at a microscale, typically in the range of micrometers (one millionth of a meter). It involves fabricating and controlling tiny optical components such as lenses, mirrors, and waveguides. These elements enable the manipulation and control of light for various purposes, including optical sensing, telecommunications, and medical imaging.

On the other hand, nanooptics operates at an even smaller scale, dealing with light on the nanometer level (one billionth of a meter). Nanooptics explores the behavior of light when it interacts with nanostructures, which are structures with dimensions in the nanoscale range. The manipulation of light at this scale has opened up a new realm of possibilities, enabling advancements in fields like nanophotonics, plasmonics, and quantum optics.
