This
method was good because it was easy to use and had a wide field of
view, but I was still concerned about the image flow due to lens
aberration at the periphery of the image, not to mention the center. It seems that the optical system of the microscope was not so well designed. After
that, several combinations of microscopes and CCDs were tried, but they
did not improve the results, and I finally settled on the following
method.
