(2) Loosen the two screws in the figure below, adjust the tilt of the splitter so that the height of
the reflected light flux (0-order light) is the same as the height of the slit on the PD ASSY.
(3) Loosen the screw in the figure below, and adjust the left/right position of the PD ASSY so that
the slit is aligned with the center of the reflected light (0-order light).
