Light source device

Abstract

A light source device includes a light source, a reflective filter and an optical absorber. The light source is used for emitting a light beam. The reflective filter is configured for selectively reflecting a first portion of the light beam emitted from the light source and for selectively transmitting a second portion thereof. The optical absorber is configured for absorbing the second portion of the light beam transmitted by said reflective filter. An optical system for an optical disk storage system is also provided. The optical system includes the light source device, an objective lens, and a detector. The objective lens is used for focusing the portion of the light beam onto an optical disk. The detector receives a return light beam reflected by the optical disk.
