Title (EN) ULTRAVIOLET SENSING APPARATUS
(FR) DISPOSITIF SERVANT A DETECTER LES ULTRAVIOLETS
Abstract:
(EN) UV sensing apparatus comprises a substantially light-proof housing (1), an aperture (1a) formed in the housing, a filter (2) positioned within the housing at the internal mouth of the aperture, a fluorescent member (3) positioned within the housing on that side of the filter remote from that adjacent to the aperture, and a light sensor (4) positioned within the housing to receive light emitted by the fluorescent member. The filter (2) is such that it substantially removes visible light, the fluorescent member (3) is such as to fluoresce when subjected to UV radiation, and the light sensor (4) is positioned so that substantially none of any electromagnetic radiation entering the housing (1) via the aperture (1a) impinges upon the light sensor.
(FR) Dispositif servant à détecter les ultraviolets et comprenant un boîtier (1) sensiblement étanche à la lumière, une ouverture (1a) pratiquée dans le boîtier, un filtre (2) placé à l'intérieur du boîtier au niveau de l'ouverture interne, un élément fluorescent (3) placé à l'intérieur du boîtier du côté du filtre et à distance du côté contigu à l'ouverture, ainsi qu'un détecteur de lumière (4) placé à l'intérieur du boîtier afin de recevoir la lumière émise par l'élément fluorescent. Le filtre (2) est conçu de façon à pratiquement supprimer la lumière visible, l'élément fluorescent (3) est conçu de façon à émettre une fluorescence quand il est soumis à un rayonnement d'ultraviolets et le détecteur de lumière (4) est placé de telle façon que l'impact du rayonnement électromagnétique pénétrant dans le boîtier (1) par l'intermédiaire de l'ouverture (1a) est pratiquement nul.
