Projector: an optical device for projecting a beam of light.

Holography: the branch of optics that deals with the use of coherent light from a laser in order to make a hologram that can then be used to create a three-dimensional image.

Cd: a digitally encoded recording on an optical disk that is smaller than a phonograph record; played back by a laser.

Spot: a lamp that produces a strong beam of light to illuminate a restricted area; used to focus attention of a stage performer.

Searchlight: a light source with reflectors that projects a beam of light in a particular direction.

Refracting Telescope: optical telescope that has a large convex lens that produces an image that is viewed through the eyepiece.

Reflecting Telescope: optical telescope consisting of a large concave mirror that produces an image that is magnified by the eyepiece.

Kaleidoscope: an optical toy in a tube; it produces symmetrical patterns as bits of colored glass are reflected by mirrors.

Pelican Crossing: an acronym for pedestrian light control; a pedestrian crossing with traffic lights that are controlled by pedestrians.

Concave Lens: a lens such that a parallel beam of light passing through it is caused to diverge or spread out.

Running Light: light carried by a boat that indicates the boat's direction; vessels at night carry a red light on the port bow and a green light on the starboard bow.

Homochromatic: (of light or other electromagnetic radiation) having only one wavelength.

Polaroid: (trade mark) a plastic film that can polarize a beam of light; often used in sunglasses to eliminate glare.

Bedazzle: to cause someone to lose clear vision, especially from intense light.

Radiography: photography that uses other kinds of radiation than visible light.

Fluorescence: light emitted during absorption of radiation of some other (invisible) wavelength.

Emit: give off, send forth, or discharge; as of light, heat, or radiation, vapor, etc..

Absorbance: (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation.

Action Spectrum: the efficiency with which electromagnetic radiation produces a photochemical reaction plotted as a function of the wavelength of the radiation.

Radiography: the process of making a radiograph; producing an image on a radiosensitive surface by radiation other than visible light.

Lightning: abrupt electric discharge from cloud to cloud or from cloud to earth accompanied by the emission of light.

Optically: in an optical manner.

Dark-Field Microscope: light microscope that uses scattered light to show particles too small to see with ordinary microscopes.

Eye Condition: the condition of the optical properties of the eye.

Mnemonic: a device (such as a rhyme or acronym) used to aid recall.

Prism Spectroscope: an optical instrument for spectrographic analysis.

Radiogram: a photographic image produced on a radiosensitive surface by radiation other than visible light (especially by X-rays or gamma rays).

Periscope: an optical instrument that provides a view of an otherwise obstructed field.

Collimate: adjust the line of sight of (an optical instrument).

Detector: any device that receives a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it in a distinctive manner.

Absorptance: a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber.
