シリンドリカルレンズが一体に形成されてなる ことを特徴とする発光装置。[Scope of Claim for Utility Model Registration] In a light emitting device using a semiconductor laser as a light source, the convergence point of the oscillated light beam differs in the semiconductor junction plane and in the plane perpendicular to it and causes astigmatism. A light emitting device made of a transparent material, characterized in that a cylindrical lens for correcting astigmatism of the emitted light beam is integrally formed in a portion of the cap through which the emitted light beam from the semiconductor laser passes.
