An optical switch is provided for switching an optical path among at least three lenses separated in the horizontal direction and among at least three lenses separated in the horizontal and vertical directions. The optical switch includes a lens holding member for holding the lens, a fixed prism optically coupled with the lens, and a movable prism movably held to the lens holding member. The movable prism is driven by an actuator between a first position whereupon the optical path is formed between one pair of lenses by using the fixed prism and a second position whereupon the optical path is formed between another pair of lenses by using the movable prism.

La présente invention concerne un commutateur optique permettant de commuter un trajet optique parmi au moins trois lentilles séparées dans la direction horizontale et parmi au moins trois lentilles séparées dans les directions horizontale et verticale. Le commutateur optique comprend un élément de support de lentille destiné à maintenir la lentille, un prisme fixe couplé de manière optique à la lentille et un prisme mobile maintenu de manière mobile sur l~élément de support de lentille. Le prisme mobile est entraîné par un actionneur entre une première position dans laquelle le trajet optique est formé entre une paire de lentilles en utilisant le prisme fixe et une seconde position dans laquelle le trajet optique est formé entre une autre paire de lentilles en utilisant le prisme mobile.
