The invention discloses a multipath light combining component comprising a first prism, a second prism and an optical glass body. The inclined plane of the first prism and the inclined plane of the second prism are glued and connected to the two ends of the optical glass body respectively to form a cuboid, wherein the two inclined planes are respectively provided with a polarization light splitting film. The first prism has a first surface and a second surface which are mutually perpendicular, and the second prism has a third surface and a fourth surface which are mutually perpendicular, wherein the fourth surface and the second surface are arranged face to face. A first 1/4 wave plate is arranged at the place parallel to the first surface, a second 1/4 wave plate is arranged at the place parallel to the second surface, and a third 1/4 wave plate is arranged at the place parallel to an opposite surface of the third surface, wherein the above 1/4 wave plates are respectively plated with a high reflection film.
