Patent ID: 7261429

Claim:
Device for illuminating an illumination field, in particular an operating field, comprising: a casing comprising at least one means for securing a light source to emit at least separate first and second light beams; at least one movable optical assembly constructed and arranged to the first light beam emitted by the light source towards the illumination field, wherein the movable optical assembly comprises: a support for securing the assembly; an optical focusing element; and a reflecting mirror constructed and arranged to reflect the first incident light beam from the at least one light source towards the optical focusing element in order to focus the first incident light beam onto an illumination plane, the reflecting mirror being movable relative to the securing support, the optical focusing element being movable relative to the securing support and comprising means for connecting the optical focusing element to the reflecting mirror for synchronised displacement of the optical focusing element and the reflecting mirror, wherein the optical focusing element is a through-aperture comprising a first dioptre lens and a second dioptre lens, the first dioptre lens being adapted for correcting optical aberrations, the second dioptre lens being adapted for making uniform the illumination over the illumination plane, the securing support being fixed to the casing; and a fixed optical assembly comprising: a fixed reflecting mirror; and a fixed optical focusing element; wherein the fixed reflecting mirror and the fixed optical focusing element are constructed and arranged to reflect the second incident beam of light emitted by the at least one light source toward the illumination field through the fixed optical focusing element, the fixed assembly being secured relative to the casing.
