OPTICAL DEVICE CAPABLE OF MINIMIZING OUTPUT VARIATION DUE TO FEEDBACK LIGHT, OPTICAL SCANNING APPARATUS, AND IMAGE FORMING APPARATUS |
摘要 |
An optical device includes a surface-emitting laser array having a plurality of light-emitting portions; a package member on which the surface-emitting laser array is disposed; and a transparent member retained on the package member and disposed on an optical path of a light beam emitted by the surface-emitting laser array. The transparent member includes an incident plane on which the light beam emitted by the surface-emitting laser array is incident. The incident plane is inclined with respect to an emitting surface of the surface-emitting laser array at a first inclination angle which is smaller than a second inclination angle at which the light emitted by one of the light-emitting portions is incident on another, most-distant one, of the light-emitting portions via reflection by the transparent member.
