Hola, 

en reprenant le TD n° 2 je me pose une petite question

Quand on dit que la face convexe est tournée vers l'air ca veut dire du côté gauche de l'axe otique du coup je comprends pas pourquoi c'est pas SC < 0 même si je sais qu'un dioptre convexe est caractérisé par un rayon  de courbure positif
