Abstract:
An automatic device for assembling a fiber collimator, the fiber collimator including a transparent tubular holder, an optical fiber having a first end surface disposed at an end of the tubular holder, and a GRIN lens having a second end surface disposed at the other end of the tubular holder, the automatic device including:a first driving table for rotating and moving the optical fiber; a second driving table for rotating and moving the GRIN lens; an image pick-up device for filming the first and second end surfaces, and outputting image data corresponding to the first and second end surfaces; and a processor receiving and processing the image data to rotate the first and second driving table so that the first and second end surfaces are parallel to each other, and move the first and second driving table so that a distance between the first and second end surfaces is equal to a predetermined value.
