Abstract

L'invention concerne un prisme de tonomètre, de préférence à usage unique, présentant une surface d'aplanation, un port d'entrée adapté pour l'émission d'une lumière incidente sur le prisme, et un port de sortie adapté pour l'émission d'une lumière de sortie sortant du prisme. La lumière entrant dans le port d'entrée est dirigée selon une trajectoire rectiligne non réfléchie à travers le prisme sur une face interne de la surface d'aplanation. La lumière réfléchie intérieurement provenant de la surface d'aplanation, suit une trajectoire rectiligne non réfléchie à travers le prisme jusqu'au port de sortie.
