失を大きくしている。In the above-mentioned prior art, the plane parallelism between the holders of the optical element array and the lens array depends on the accuracy of attachment to the holders that hold them and the processing accuracy of the surfaces to be joined to the holders. However, the vertical accuracy of the optical axis of the objective lens optical axis with respect to the lens array plane is controlled by the accuracy of the jig for chucking the holder and the accuracy of attachment to the jig for chucking.
Mainly, the vertical precision deviation between the optical axis of the objective lens optical axis and the plane of the lens array due to the mounting accuracy of the lens array holder to the chucking jig is not controlled during the assembly work. The assembly coupling loss of is increased.
