Abstract:
1. An optical combiner comprising an optical component and a plastic body, the optical component comprising a first optical filter, a second optical filter, and a base, the first optical filter reflecting light having a first wavelength and being transparent to light having a second wavelength and light having a third wavelength, the second optical filter reflecting light having the second wavelength and being transparent to light having the third wavelength, the base having a first main surface and a second main surface, the base being transparent to light having the second wavelength and light having the third wavelength, the first optical filter being provided on the first main surface, the second optical filter being provided on the second main surface, the plastic body having first, second, and third surfaces, the first surface providing first, second, and third lenses, the optical component is surrounded by the plastic body in section including optical axes of light L light L light L combined light LM, such that light from the first lens is connected to an optical path to the second surface through the first optical filter, light from the second lens is connected to the optical path through the second optical filter, and the third surface is a reflecting surface for connecting light from the third lens to the optical path, the reflecting surface having a reflection film consisting of aluminum or gold, and the optical path between the second optical filter and the third surface and the first, second, and third lenses are formed with the plastic body.
