Abstract

The invention relates to a device that is used to illuminate an object, comprising a light source (12) which is adapted to emit first (Fμ0) and second (Fμmin, Fμmax) electromagnetic beams. The aforementioned first beams (Fμ0) have a wavelength that is located in a first domain within the visible spectrum while the second beams (Fμmin, Fμmax) have a wavelength (μmin, μmax) that is located outside of said first domain. The inventive device comprises a flux collector (14) which is designed to direct the beams towards the field to be illuminated (4). Said flux collector (14) comprises a diffractive optical element (16) which is disposed in the course the beams follow from the light source (12) towards the field to be illuminated (4). The invention is suitable for lighting devices used in operating theatres.
