Abstract

L'invention concerne les appareils et instruments de mesure. Le dispositif faisant l'objet de l'invention est caractérisé notamment en ce que le guide de lumière 2 traverse la tuyère 3 de l'analyseur photoélectrique d'aérosols 1, et que son bout disposé à l'intérieur de l'analyseur photoélectrique d'aérosols 1 est réalisé sous forme d'une bille 5 afin d'assurer une distribution uniforme du flux lumineux dans la zone de travail de l'analyseur photoélectrique d'aérosols. L'invention s'applique notamment aux analyseurs de la teneur en poussières de l'air, utilisés par exemple dans les mines, les ateliers de montage de précision, etc.
