ABSTRACT:
An optical apparatus (23) for emitting light is constituted by a fixation holder (8) fixed to a predetermined positioning fixation jig via a fixation plate (8a), a lens-barrel (10), fitted on a cylindrical portion of the fixation holder (8) via an annular gap (19), and formed of a transparent material, for holding a collimator lens (2), and a semi-conductor laser light source (1) fitted under pressure in the fixation holder (8). An ultraviolet curing adhesive (18) is uniformly filled in the gap (19). Before the ultraviolet curing adhesive (18) is cured, the lens-barrel (10) is movable in an optical axis direction (Z) and in two-dimensional directions (directions of arrows X and Y) on a plane perpendicular to the optical axis direction (Z) with respect to the fixation holder (8).
