optics - Computer Definition
The branch of physics dealing with the nature and properties of electromagnetic energy in the light spectrum and the phenomena of vision.

- The theory of electro-optics received great attention from Kelvin, Maxwell, Rayleigh, G.
- Prisms, and that familiar experiments in optics could be repeated with electric waves which could not affect the eye.
- There is a great deal of practical information on lenses in connexion with the camera and other optical instruments, and the book is valuable as a repertory of early practical optics, also for the numerous references to and extracts from previous writers.
- It accordingly comments on the Sphaerica of Theodosius, the Moving Sphere of Autolycus, Theodosius's book on Day and Night, the treatise of Aristarchus On the Size and Distances of the Sun and Moon, and Euclid's Optics and Phaenomena.
- Attempts have been made, principally founded on some remarks of Huygens, to show that Descartes had learned the principles of refraction from the manuscript of a treatise by Willebrord Snell, but the facts are uncertain; and, so far as Descartes founds his optics on any one, it is probably on the researches of Kepler.
