System and method for measuring eccentricity of fiber lens device

A method for measuring an eccentricity of a fiber lens device, the fiber lens device comprising a lens and defining a fiber receiving hole, the method comprising:

• providing a system, the system comprising a measuring fixture, an image capturing device and an analysis device, the measuring fixture comprising a measuring surface, the measuring surface defining an insertion hole and three measuring holes, the three measuring holes arranged in vertexes of an equilateral triangle, the measuring fixture further comprising a rod in the insertion hole, a circumcenter of the equilateral triangle formed by the three measuring hole being concentric with the rod;
• inserting the rod into the fiber receiving hole;
• capturing an image of the measuring surface and the fiber lens device by using the image capturing device;
• and
• analyzing the image by using the analysis device to acquire a distance between the circumcenter of the equilateral triangle formed by the three measuring hole and a center of the lens, and to determine whether the distance is in a predetermined range.
