Abstract

Spectrophotomètre destiné à mesurer l'intensité de lumière pour chacune des longueurs d'onde d'un faisceau de lumière. Il comporte un faisceau 1 de fibres optiques 15 dont les extrémités sont fixées au filtre d'interférence 3 sur lequel sont scellées les photodiodes 17 qui reçoivent la lumière transmise à travers le filtre, chaque photodiode fournissant un signal électrique proportionnel à l'intensité de lumière qu'elle reçoit. Ce spectrophotomètre se distingue des spectrophotomètres classiques par le fait qu'il ne comporte pas de parties mobiles.
