LASER MODULE

摘要

[Objective] To prevent change in a direction of an optical axis of a split light within a plane parallel to a surface on which the beam splitter is installed. [Means] A laser module including a laser light source that emits a laser light and a beam splitter that splits a portion of the laser light emitted from the laser light source. The beam splitter includes a first reflective surface and a second reflective surface that are parallel to each other. The first reflective surface transmits a first portion of the laser light and reflects a second portion of the laser light to the second reflective surface. The second reflective surface receives the second portion of the laser light from the first reflective surface and reflects received laser light in a direction parallel to the laser light emitted from the laser light source.
