(FR) SYSTEME DE LECTURE OPTIQUE POUR UNE METHODE D'ANALYSE IMMUNOLOGIQUE
Abstract
(EN)
A low cost optical system which incorporates a low ultraviolet output tungsten halogen light source and solid state photodetectors and circuitry in such a way as to provide reliable fluorometric test results. The attainment of reliable results using such components is made possible by incorporating highly ultraviolet transmissive optics to maximize ultraviolet light throughput and by using solid state circuitry together with a filter wheel having both light blocking and light passing regions in a manner which fully accounts for noise and dark signals associated with solid state photodetectors.
(FR)
Il s'agit d'un système optique à faible coût qui comprend une source de lumière halogène tungstène à faible sortie d'ultraviolets et des photodetecteurs à semiconducteurs ainsi que des circuits capables de fournir des résultats d'essai fluorométriques fiables. L'obtention de résultats fiables en utilisant de tels composants est rendue possible en intégrant une optique à forte transmission d'ultraviolets pour maximiser la lumière ultraviolette passée et en utilisant des circuits à semiconducteurs en association avec une roue à filtres ayant tous deux des zones d'arrêt et des zones de passage de la lumière de sorte à tenir entièrement compte des signaux de bruit et d'obscurité associés aux photodétecteurs à semiconducteurs.
