Abstract
An optical combiner in which fewer parts are used comprises an optical component and a plastic body. The component comprises: a first filter reflecting first light having a first wavelength and being transparent to second light having a second wavelength and third light having a third wavelength; a second filter reflecting second light and being transparent to third light; and a base transparent to second light and third light. The first filter and the second filter are provided on opposed surfaces of the base. The plastic body has first, second, and third surfaces, and the first surface provides first, second, and third lenses. The component is provided in the plastic body such that light from the first lens is connected to a path to the second surface through the first filter and light from the second lens is connected to the path through the second filter. The third surface is a reflecting surface for connecting light from the third lens to the path.
