International Classification:

G02B 6/42
G01N 21/01

US Classification:

385 37, 356 731

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.

Assignee:

PROMET INTERNATIONAL, INC. - Shoreview MN

International Classification:

G01B 9/02

US Classification:

356450

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.

Abstract:

Blood separation systems and methods are provided for controlling the interface between separated blood components. The system includes a centrifuge assembly having a light-transmissive portion, a light reflector, and a fluid processing region therebetween. An optical sensor system emits a scanning light beam along a path toward the light-transmissive portion, which transmits at least a portion of the scanning light beam to the fluid processing region and the light reflector. The light reflector reflects at least a portion of the scanning light beam toward the optical sensor system along a path substantially coaxial to the path of the scanning light beam from the optical sensor system toward the light-transmissive portion of the centrifuge assembly. The scanning light beam may be a white light beam or narrow spectrum beam. The reflected beam may be directed through the optical sensor system via optical fibers.
