摘要

A dot-sighting device includes a light source, a beam splitter and a reflective element. The light source emits light. The beam splitter includes a surface that reflects at least a portion of a first light component of the light and transmits at least a portion of a second light component. The reflective element reflects at least a portion of the first light component reflected by the surface of the beam splitter toward the beam splitter. The light reflected by the reflective element includes the second light component.
