Abstract[English]
Certain embodiments provide an arm assembly (120) for a wide angle viewing system (100) for an ophthalmic microscope. The arm assembly (120) comprises an articulated arm (130) configured to be coupled to a reduction lens module (110), and a loupe lens turret (140) coupled to the articulated arm (130). The loupe lens turret (140) comprises a body (141), a base (150) rotationally coupled to the body (141), and a spring (200) coupled to the body (141) and the base (150). The base (150) is configured to receive a removable loupe lens assembly (160, 170). The spring (200) is configured to a first spring force and a second spring force. The first spring force rotates the base (150) in a first direction and holds the base (150) against the body (141) in a first position. The second spring force rotates the base (150) in a second direction and holds the base (150) against the body (141) in a second position.[French]
Certains modes de réalisation de l'invention concernent un ensemble bras (120) pour un système de visualisation grand angle (100) pour un microscope ophtalmique. L'ensemble bras (120) comprend un bras articulé (130) conçu pour être couplé à un module de lentille de réduction (110), et une tourelle de lentilles de loupe (140) couplée au bras articulé (130). La tourelle de lentilles de loupe (140) comprend un corps (141), une base (150) couplée en rotation au corps (141), et un ressort (200) couplé au corps (141) et à la base (150). La base (150) est conçue pour recevoir un ensemble lentille de loupe amovible (160, 170). Le ressort (200) est conçu pour une première force de ressort et une deuxième force de ressort. La première force de ressort fait tourner la base (150) dans une première direction et maintient la base (150) contre le corps (141) dans une première position. La deuxième force de ressort fait tourner la base (150) dans une deuxième direction et maintient la base (150) contre le corps (141) dans une deuxième position.
