Abstract
The invention relates to an optical system having a light source, configured to emit electromagnetic radiation; a waveguide, configured to guide the electromagnetic radiation in a guiding direction and having an input; and an injection device, configured to inject the electromagnetic radiation emitted by the light source at the input of the waveguide. The injection device consists of a single dioptric interface designed to focus the electromagnetic radiation emitted by the light source at the input of the waveguide.
