  • Patent number: 9007572
    Abstract: An inspection system includes optical components for operating the inspection system in an interference fringe imaging mode and a microscope imaging mode. The inspection system further includes at least one optical light source configured to emit a first wavelength of light to operate the inspection system in the interference fringe imaging mode and configure to emit a second wavelength of light to operate the inspection system in the microscope mode. The first wavelength of light is different from the second wavelength of light.

  • Patent number: 8705041
    Abstract: An optical probe has optical components of an interferometer and includes an optical axis, at least one optical source for emitting light along an illumination path that is at least partially coaxial with the optical axis, a first beam splitter and a first lens. The first beam splitter intersects the optical axis and splits the light from the at least one optical source into a first beam for traveling along a reference path that is coaxial with the optical axis to a reference surface and a second beam for traveling along a test path that is coaxial with the optical axis to a specimen. The first lens is interposed along the reference path.

  • Patent number: 8306760
    Abstract: A computing system includes an interferometer and a processor. The interferometer is configured to generate at least two phase shifted images of an optical fiber specimen. The processor is configured to acquire the at least two phase shifted images from the interferometer, generate a first intermediate data set based on the at least two acquired phase shifted images and perform two-dimensional defect detection on the first intermediate data set.

  • Patent number: 7801407
    Abstract: 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.
