Abstract[English]
A spectroscopic absorption cell suitable for use with a divergent light source, the cell including: an elongate chamber having reflective sidewalls; a first mirror positioned at a first end of the chamber, the first mirror having a first aperture for receiving light into the chamber; a second mirror positioned at an opposite second end of the chamber, the second mirror having a second aperture for allowing light to exit the chamber. The first and second mirrors have reflective surfaces opposing each other and the reflective sidewalls cooperate with the first and second mirrors to contain light within the chamber, such that a majority of light rays entering the chamber make multiple passes of the cell between the mirrors.[French]
L'invention concerne une cellule d'absorption spectroscopique appropriée pour être utilisée avec une source de lumière divergente, la cellule comprenant : une chambre allongée comportant des parois latérales réfléchissantes ; un premier miroir positionné à une première extrémité de la chambre, le premier miroir comportant une première ouverture de réception de lumière dans la chambre ; un second miroir positionné au niveau d'une seconde extrémité opposée de la chambre, le second miroir comportant une seconde ouverture permettant à la lumière de sortir de la chambre. Les premier et second miroirs comportent des surfaces réfléchissantes opposées l'une à l'autre et les parois latérales réfléchissantes coopèrent avec les premier et second miroirs pour contenir de la lumière à l'intérieur de la chambre, de sorte qu'une majorité de rayons lumineux pénétrant la chambre passent de multiples fois par la cellule entre les miroirs.
