PROBLEM TO BE SOLVED: To provide an optical assembly capable of adjusting the optical axis of each laser beam emitted, respectively, from a red LD, a green LD and a blue LD accurately each other.SOLUTION: An optical assembly 10A includes a red LD11, a green LD12 and a blue LD13. The red LD, green LD and blue LD are mounted on the principal surface 30a of a base member 30 via sub-mounts 21-23, respectively. A collimate lens 41 collimates red laser light Lfrom the red LD, a collimate lens 42 collimates green laser light Lfrom the green LD, and a collimate lens 43 collimates blue laser light Lfrom the blue LD. The collimate lenses 41-43 are mounted on the principal surface via subbase members 51-53. Optical axes of the laser light L, L, Lare at the substantially same height with reference to the principal surface.SELECTED DRAWING: Figure 1 |
