Abstract
(EN)
In one embodiment, the invention is spectrophotometer with a light emitting diode illuminator. In one embodiment, a spectrophotometer for characterizing a reflectance spectrum of a specimen includes an optical assembly for illuminating the specimen, where the optical assembly includes at least one light emitting diode. A measurement head is coupled to the optical assembly for collecting light reflected by the specimen, and a spectrum analyzer is coupled to the measurement head for performing spectral analysis of the collected light into a plurality of spectral bands. A reference channel provides illumination from the optical assembly to the spectrum analyzer, while a test channel provides the collected light from the measurement head to the spectrum analyzer.

Dans un mode de réalisation, l'invention concerne un spectrophotomètre comprenant un dispositif d'éclairage à diodes électroluminescentes. Dans un mode de réalisation, un spectrophotomètre pour caractériser un spectre de réflexion d'un échantillon, comprend un ensemble optique qui sert à éclairer l'échantillon, l'ensemble optique comprenant au moins une diode électroluminescente. Une tête de mesure est couplée à l'ensemble optique pour récupérer la lumière réfléchie par l'échantillon, et un dispositif d'analyse de spectre est couplé à la tête de mesure pour réaliser une analyse spectrale de la lumière récupérée, en une pluralité de bandes spectrales. Un canal de référence achemine l'éclairage de l'ensemble optique au dispositif d'analyse de spectre, alors qu'un canal d'essai achemine la lumière récupérée de la tête de mesure au dispositif d'analyse de spectre.
