Abstract
An optical device able to change the direction of propagation of a light beam. The optical device allows a wide range of adjustment of the direction of the light beam, said optical device including, in the direction of propagation of the light beam, an overall divergent group of lenses and an overall convergent group of lenses. The overall divergent group of lenses contains, in the direction of propagation of the light beam, a fixed lens, and an optical module comprising at least one movable optical element able to change the direction of propagation of the light beam emerging from the overall divergent group of lenses.
