Abstract
In a retainer holding a plurality of optical transmission members at given positions, a position of an optical center of each of the optical transmission members is measured at a high measuring accuracy. In this case, a lens system forming a beam waist in its output beam is arranged so as to oppose to an end face of each of the optical transmission members, and then the output beam is input to the optical transmission member, and subsequently a position of the lens system is measured when a light intensity of a beam emanated from the optical transmission member is maximum, and thereafter a position of the optical transmission member is calculated from the measured value.
