The optical pickup includes: a light source; an optical bench on which the light source is mounted; a focusing member including an objective lens, focusing light emitted from the light source to form a light spot on an optical information storage medium; and an optical path forming member having a transparent block that includes a light entrance/exit surface on which the optical bench and the focusing member are arranged, a first reflection surface, and a second reflection surface opposing the first reflection surface, where the optical path forming member directs the light emitted from the light source toward the objective lens by reflecting the light emitted from the light source on the first and second reflection surfaces. The optical pickup satisfies the requirement for smaller, slimmer design and can be integrated using semiconductor manufacturing processes.

    摘要： An optical system and an information apparatus using the optical system are provided. The optical system includes an optical bench on which a light source and a photodetector including a main photodetector receiving the light are mounted. A lens unit is coupled to the optical bench, and an optical path separating member separates an optical path of light emitted from the light source and propagating toward the lens unit and an optical path of light incident from the lens unit. The optical system may include a monitor photodetector and/or an optical path forming unit coupled to the optical bench. The monitor photodetector receives a portion of the light emitted from the light source. The optical path forming unit includes a first mirror reflecting the light emitted from the light source and a second mirror reflecting the light incident from the lens unit and reflected by the first mirror.
