An optical inspection system includes an optical inspection device and an
interface. The optical inspection device houses optical imaging
components that acquire microscope visual images and acquire interference
fringe images of a plurality of optical specimens along an optical path.
The optical path is located along an optical axis of the optical
inspection device. The interface is coupled to the optical inspection
device and is configured to removably engage a polishing work holder that
supports the plurality of optical specimens. The interface allows an
optical specimen axis of each of the plurality of optical specimens and
the optical axis of the optical inspection device to be aligned.
