Abstract
An optical coupling lens includes a refraction surface, a first total reflection surface, a second total reflection surface, a first aligning member and a second aligning member. The refraction surface, the first total reflection surface and the second total reflection surface are orderly connected end to end. The first aligning member and the second aligning member are formed on the refraction surface.
