LIGHT SOURCE DEVICE, OPTICAL SCANNING DEVICE, AND IMAGE FORMING APPARATUS

摘要

A light source device includes: a light source; a package member that holds the light source; a splitting element that is arranged on an optical path of a light beam output from the light source and splits the light beam into a first light beam and a second light beam; and a cap member that holds the splitting element so that the surface of the splitting element is inclined with respect to a plane orthogonal to a traveling direction of the light beam output from the light source and that is attached to the package member to seal the light source.
