Laser-diode-based source of monochromatic light

摘要

In a light projector including a laser diode module suitable for forming a light bundle of color and dimensions that are determined from parallel light beams from each of the laser diodes in the module, there is provided a light-tight box, an optical system constituted by an off-axis parabolic mirror for receiving the light bundle and for focusing it, after reflecting it in a perpendicular direction onto the inlet of a sole outlet optical fiber of the box.
