| 摘要 |
A multi-channel optical communication lens system, which is disposed between a plurality of arranged optical transmission lines and a plurality of photoelectric elements which is arranged facing respective ones of the optical transmission lines and transmit or receive optical signals, and which couples the optical signals between each of the optical transmission lines and each of the photoelectric elements thereto respectively, includes a first convex lens disposed at a location which makes the optical signals focus on end faces of the arranged optical transmission lines or a vicinity thereof, and a second convex lens disposed at a location which makes the optical signals focus on the photoelectric elements. Both of the first and second convex lenses includes an aspherical surface on one side thereof and a nonaxisymmetric aspherical surface on another side thereof.
