Abstract

An optical coupling lens which can reveal its own coefficient of signal attenuation 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 connected end to end in order. The first aligning member and the second aligning member are formed on the refraction surface.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An optical coupling lens comprising:
 a lens member with:   a refraction surface having a first refraction surface side and a second refraction surface side, opposite to, and substantially parallel with, the first refraction surface side;   a first total reflection surface having a first side and a second side opposite to, and substantially parallel with, the first side; and   a second total reflection surface having a first side and a second side opposite to, and substantially parallel with, the first side;   a first aligning member; and   a second aligning member;   wherein, the first refraction surface side is connected to the first side of the first total reflection surface, the second refraction surface side is connected to the first side of the second total reflection surface and the second side of the first total reflection surface is connected to the second side of the second total reflection surface; and   wherein, the first aligning member and the second aligning member are formed on the refraction surface.   
     
     
         2 . The optical coupling lens of  claim 1 , wherein an included angle between the first total reflection surface and the refraction surface is about  45  degrees, an included angle between the second total reflection surface and the refraction surface is about  45  degrees, and an included angle between the first total reflection surface and the second total reflection surface is about  90  degrees. 
     
     
         3 . The optical coupling lens of  claim 1 , wherein the first aligning member and the second aligning member are convex lenses. 
     
     
         4 . The optical coupling lens of  claim 1 , wherein the first aligning member and the second aligning member are Fresnel lenses.
