Alphabetical list of terms

Record 1 2023-05-16

English

Subject field(s)
  • Lighting
  • Optics
DEF

An UV-A radiation source, generally a mercury vapour discharge lamp, with the bulb(high-pressure radiation source) or tube(low-pressure radiation source) made from light-absorbing, but UV-A-transmitting, filter glass.

OBS

The glass filter appears almost black in colour.

OBS

blacklight lamp; ultraviolet radiation source: terms and definition standardized by the International Organization for Standardization (ISO).

Key term(s)
  • black light lamp

French

Domaine(s)
  • Éclairage
  • Optique
DEF

Source d'UV-A, généralement composée d'une lampe à décharge à vapeur de mercure comportant une ampoule (lampe haute pression) ou un tube (lampe basse pression) en verre filtrant absorbant la lumière, mais laissant passer les UV-A.

OBS

Le verre filtrant semble presque noir.

OBS

source de lumière noire; source de rayonnement ultraviolet : termes et définition normalisés par l'Organisation internationale de normalisation (ISO).

Record 2 2013-01-28

English

Subject field(s)
  • Electromagnetic Radiation
  • Optics
  • The Eye
  • The Skin
DEF

A compact xenon arc lamp, operated in a pulsed mode, usually filtered to emit visible and near-infrared radiation.

OBS

Although lasers can provide an intense pulsed source of light, when used in the medical or paramedical field, the term is restricted to xenon arc lamps. These have a broad spectral emission. The radiation emitted can be filtered to restrict the emission to the UV, visible or near-IR regions of the electromagnetic radiation spectrum.

OBS

intense pulsed light source; IPL: term, abbreviation and definition standardized by the International Organization for Standardization (ISO).

Key term(s)
  • intense pulsed source of light
  • hi intensity pulsed light source

French

Domaine(s)
  • Rayonnements électromagnétiques
  • Optique
  • Oeil
  • Appareil cutané
DEF

Lampe compacte à arc au xénon, utilisée en mode pulsé, généralement munie de filtres pour émettre un rayonnement visible et de proche infrarouge.

OBS

Bien que les lasers puissent constituer une source de lumière intense pulsée, lorsqu'ils sont utilisés dans le domaine médical ou paramédical, ce terme est réservé aux lampes à arc au xénon. Elles ont un large spectre d’émission. Le rayonnement émis peut être filtré pour limiter l’émission aux domaines UV et visible ou au domaine de proche infrarouge du spectre de rayonnement électromagnétique.

OBS

source de lumière intense pulsée; LIP : terme, abréviation et définition normalisés par l'Organisation internationale de normalisation (ISO).

Record 3 1996-04-04

English

Subject field(s)
  • Analytical Chemistry
CONT

... monochromatic UV photometer available from Du Pont; similar designs are widely used in modern LC. UV radiation at 254 nm from a low-pressure mercury lamp shines on the entrance of a flow cell and is transmitted through this sample cell and strikes the analytical prototube. Radiation from the source also is directed through a neutral-density filter, and then to the reference photocell. Current from these photocells is fed to log amplifiers, which generate an output linear with solute concentration. The output signal to the recorder normally is attenuated with a simple bridge network.
