Laser light source device and surface inspection apparatus employing the same

摘要

In a laser light source device (2), a light source unit (11) is constructed by one condenser lens (14) for condensing a laser beam emitted from one semiconductor Laser (12), another condenser lens (15) for condensing a laser beam emitted from another semiconductor laser (13), and a focusing lene (17) for focusing and projecting the laser beam condensed by one condenser lens and the laser beam condensed by another lens onto an incident face (16a) of one light guiding means. <IMAGE>
