Abstract

La présente invention concerne un module de verre protecteur conçu pour être adapté sur l'objectif principal (2) d'un microscope opératoire (1). Le module (6b) comporte un verre protecteur sphérique (5) qui présente une puissance de 0 dpt. Ce verre protecteur est relié à un élément à draper. Dans un autre mode de réalisation, le module (6c, 6d) présente un système de verre protecteur composé de deux composants optiques (13a, 14a; 13b, 14b). Une partie de l'élément à draper (10a, 10b) est pincé de force en sandwich entre les composants (13a, 14a; 13b, 14b), formant ainsi une région de feuille (10a) essentiellement non plane. Ce système global présente également une puissance de 0 dpt. Le module de verre protecteur (6b, 6c, 6d) de construction plane est utilisé avec un élément à draper (10, 10a, 10b) qui est fixé ou intégré à lui, en tant que dispositif de maintien d'état stérile pour les objectifs principaux (2) de microscopes opératoires (1).
