* Optical aberration, an imperfection in image formation by an optical system

This phenomenon, known as gravity darkening or the von Zeipel effect, was confirmed for Altair by measurements made by the Navy Prototype Optical Interferometer in 2001, and analyzed by Ohishi et al.

This includes the Optical Microscope, Transmission Electron Microscope, Scanning Electron Microscope, Fluorescence Microscope, and by Confocal Microscopy.

Optical technology, such as the telescope, sextant and other devices that use telescopes, allowed for accurate surveying of land and the ability of mapmakers and navigators to find their latitude by measuring angles to the North Star at night or the sun at noon.

** Self-focusing, an effect due to the Optical Kerr effect ( and possibly higher order nonlinearities ) caused by the spatial variation in the intensity creating a spatial variation in the refractive index

** Self-phase modulation ( SPM ), an effect due to the Optical Kerr effect ( and possibly higher order nonlinearities ) caused by the temporal variation in the intensity creating a temporal variation in the refractive index

Optical theory progressed in the mid-17th century with treatises written by philosopher René Descartes, which explained a variety of optical phenomena including reflection and refraction by assuming that light was emitted by objects which produced it.

Optical cards were produced by Landis + Gyr and Sodeco from Switzerland and were popular early phonecards in many countries with first optical phonecards successfully introduced in 1977 in Belgium.

Astrophysicist Takahiro Sumi of Osaka University in Japan and colleagues, who form the Microlensing Observations in Astrophysics ( MOA ) and the Optical Gravitational Lensing Experiment ( OGLE ) collaborations, carried out a study of microlensing which they published in 2011.

Founded in 25 July 1917 as Nippon Kōgaku Kōgyō Kabushikigaisha ( 日本光学工業株式会社 " Japan Optical Industries Co., Ltd ."), the company was renamed Nikon Corporation, after its cameras, in 1988.

Founded in 1917 as Nippon Kōgaku Kōgyō Kabushikigaisha ( 日本光学工業株式会社 " Japan Optical Industries Corporation "), the company was renamed Nikon Corporation, after its cameras, in 1988.

The name Nikon, which dates from 1946, is a merging of Nippon Kōgaku ( 日本光学: " Japan Optical ") and Zeiss ' brand Ikon.

Another early brand used on microscopes was Joico, an abbreviation of " Japan Optical Industries Co ".
