Abstract

PURPOSE:To make the use of a general light source of white light, green light, or the like possible, by using an optical mixer which superposes invisible laser beam and visible rays in a waveguide means and emits them. CONSTITUTION:An optical mixer 21 consists of a laser beam entrance 23 to which visible rays 27 are led, a mixing path where both light fluxes are superposed, and an exit 24 from which laser beam 8 made visible are emitted. Infrared laser beam 3 is converged by a beam converging and leading-in means such as a condenser lens 13 and are led to the laser beam entrance 23. It is desirable that the focus position of infrared laser rays 3 is formed before the visible ray entrance 22. Meanwhile, one end of an optical fiber 26 is inserted to the visible ray entrance, and visible rays 27 are led through a condenser lens 28 from the other end.
