Abstract
Une source lumineuse de thérapie photodynamique comporte une ampoule, un ensemble de lentilles de condensation et un ensemble de filtres. Ce dernier comprend les éléments suivants disposés sur le trajet optique : (1) un filtre passe-haut qui élimine les lumières dont les longueurs d'onde sont inférieures à une première valeur ; (2) un filtre dichroïque passe-bas qui élimine les lumières dont les longueurs d'onde sont supérieures à une deuxième valeur ; et (3) un miroir dichroïque qui reflète les lumières dont les longueurs d'onde se situent entre la première et la deuxième valeurs de longueurs d'onde et qui transmet le rayonnement infrarouge. Un ensemble de lentilles de sortie dirige la lumière qui traverse le filtre passe-haut et le filtre dichroïque passe-bas, et qui est reflétée par le miroir dichroïque, vers un patient subissant une thérapie photodynamique. L'ensemble de lentilles de condensation et l'ensemble de lentilles de sortie brouillent le faisceau pour veiller à ce que ce patient soit éclairé par une lumière à intensité et caractéristiques spectrales (couleur) hautement uniformes sur l'ensemble de la zone éclairée.
