Abstract:
1. An optical coupling module comprising: a reflection member comprising a first surface, a second surface perpendicularly connected to the first surface, and a reflection surface obliquely interconnected between the first surface and the second surface; a first assembled member comprising a first optical surface, the first assembled member detachably mounted on the first surface, the first optical surface being parallel to the first surface; a second assembled member comprising a second optical surface, the second assembled member detachably mounted on the second surface, the second optical surface being parallel to the second surface; a plurality of first converging lenses arranged on the first optical surface, optical axes of the first converging lenses being perpendicular to the first surface; and a plurality of second converging lenses arranged on the second optical surface and corresponding to the second converging lenses, optical axes of the second converging lenses being perpendicular to the second surface; wherein the reflection surface is configured for reflecting parallel light beams from the first converging lenses toward the corresponding second converging lenses and for reflecting parallel light beams from the second converging lenses toward the corresponding first converging lenses, wherein the first surface defines a first groove, the first assembly member comprises a first body portion and a first protrusion protruding from the first body portion, the first protrusion engages in the first groove, the first body portion comprises a first assembly surface contacting the first surface of the reflection member and a connection surface opposite to the first assembly surface, the first protrusion protrudes from the first assembled surface, the connection surface defines a cavity, the first optical surface is located at a bottom of the cavity, and the first protrusion is aligned with the cavity.
