<p>The extended optical source comprises an elongate bar (1) with one lateral surface (1B) and two end surfaces (1A), and at least one optical emitter (5) placed in front of at least one of said end surfaces (1A), in such a way as to emit an optical beam toward said end surface. The bar is made from a material optically transparent at the emission wavelength of the optical emitter (5). At least one diffusing strip (11) is provided along the longitudinal development of said bar, on the lateral surface (1B) thereof, for the extraction of the light from the bar.</p> |
