Definition

Optics – Branch of physical science concerned with the transmission, generation, manipulation, and detection of electromagnetic radiation in the wavelength range from vacuum ultraviolet to the far infrared. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.

NASA Interest

Exhaustive Interest : Theories of light transmission and lenses, light absorption, reflection, and scattering as they relate to aeronautics, astronautics, and space sciences.

Selective Interest : Optics and light phenomena with potential aerospace use.

Negative Interest : Industrial, commercial, and household applications of optics and light phenomena, lenses, and eyeglasses.
