ABSTRACT:
A light source device has a semiconductor laser element, a collimator lens, a lens barrel for holding the collimator lens, first and second lens barrel support member and a laser support member. The lens barrel support members are formed of the same type of material as that of the lens barrel and engage the lens barrel at a surface parallel to the optical axis of the collimator lens. The laser support member is formed of a different type material from that of the lens barrel support members, and joins the lens barrel support members at a surface perpendicular to the optical axis of the collimator lens.
