optics

(science and technology regarding visible light)

The word optics refers to the science and technology regarding the behavior and handling of visible light, the term being used for the principles and mechanisms of telescopes and telescopic instruments such as cameras/imagers and spectrographs. It is also used for portions of ultraviolet and infrared spectra that are adjacent to visible light, and are handled using virtually the same equipment. Thus the adjective optical easily also refers to near infrared and near ultraviolet.

The word optics is often used to mean an optical device or the optical portion or aspect of a device. Further from visible light, there are often parallels regarding design and sometimes the word optics is borrowed.
