Abstract
In a method of adjusting an optical axis of an optical fiber to a beam axis of a light beam of an optical element, light power values are measured at a plurality of positions to define a specific function which is determined by the light power values and the positions and which has a specific maximum value at a specific maximum position. The optical fiber and the optical element are relatively moved to the specific maximum position to measure a measured light value at the specific maximum position. The specific function is modified by the use of the measured light value to relatively move the optical fiber and the optical element to a final position. Such adjustment may be made three-dimensionally and/or rotatably. On rotatable adjustment, a predetermined value may be set instead of the specific maximum value.
