That branch of physical science which treats of the nature and properties of light, the laws of its modification by opaque and transparent bodies, and the phenomena of vision.
Elements (glasses, mirror, telescope...) used to see or visualise something.
The light-emitting or light-controlling components of a light fixture (reflector, refractor, lens, louvers, etc.)
Branch of physics that deals with light and the electromagnetic radiation; certain areas are dispersion, absorption spectra, reflection, and refraction.
The science of the origin, nature and laws of light.
the science that deals with light and closely associated phenomena.
The study of the properties of visible light, i.e., the portion of the electromagnetic spectrum with wavelengths between 360 and 780 nm ( nm = m/s).
The quantitative measure of brightness of a light source or an illuminated surface, equal to luminous flux per unit solid angle emitted per unit projected on the surface.
The science dealing with the behavior of light.
A term referring to the light-controlling components of a luminaire (such as reflectors, refractors, lenses, and louvres).
The study of nature & properties of light.
the branch of physics that studies the physical properties of light
a great outfit to deal with
the science that deals with the properties of light; in this case specifically dealing with light in the water column and how it is affected by the presence/absence of algae
A term referring to the components of a light fixture (such as reflectors, refractors, lenses, louvers) or to the light emitting or light-controlling performance of a fixture.
The scientific study of light rays and how they relate to vision.
Describes the properties of light, how it behaves and how it relates with matter. (But 'optic' relates to the eye or vision.)
A term that refers to the laser engraving system's mirrors and lenses that are used to direct and focus the laser beam.
(noun) Any of the elements (as lenses, mirrors, or light guides) of an optical instrument or system.
The branch of physical science that deals with the properties and phenomena of both visible and invisible light and with vision.
That branch of physical science concerned with vision and certain phenomena of electromagnetic radiation in the wavelength range extending from the vacuum ultraviolet at about 40 nm to the far-infrared at 1 mm. Now being replaced by the more inclusive term photonics.
The science covering the behavior and characteristics of light.
