    Abstract: A transmitted light intensity measurement unit for measuring a concentration of fluid flowing through a duct comprises: a light source for supplying light into the duct from a light supply part on a surface of the duct; a light receiving element for receiving the light, which has been passed from the light supply part through the duct wall and the fluid inside the duct, at a light receiving part located on an opposite side in a diametrical direction of the duct relative to the light supply part, and outputs a signal indicating an intensity of the light; and a light-transmissive member disposed on at least one light path among a light pass between the light source and the light supply part and a light pass between the light receiving element and the light receiving part, abutting and closely contacting the duct wall by an elastic deformation of the duct wall.

    Abstract: A fabrication cluster can be controlled using optical metrology. A fabrication process is performed on a wafer using a fabrication cluster. A photonic nanojet, an optical intensity pattern induced at a shadow-side surface of a dielectric microsphere, is generated. An inspection area on the wafer is scanned with the photonic nanojet. A measurement is obtained of the retroreflected light from the dielectric microsphere as the photonic nanojet scans the inspection area. The existence of a structure in the inspection area is determined with the obtained measurement of the retroreflected light. One or more process parameters of the fabrication cluster is adjusted based on the determination of the existence of the structure in the inspection area.

    Abstract: A bent capillary flow cell with protruding end bulbs coaxial with centerline of an elongated center cylindrical section of capillary tubing. The bulbs provide a high light throughput entrance window for the cell. Light is piped along the elongated center section by total internal reflection at the outside surface of the cell wall. An external light absorbing band is placed in optical contact with outer surface of the cell wall over a transition cone region between the bulb and center cylindrical section of the cell. Each of the external light absorbing bands extend a short prescribed distance over the cylindrical wall to absorb light rays that would otherwise be light piped within the cell wall and have little exposure to the liquid in the cell.

    Abstract: An analytical instrument may have multiple distinct channels. Such may include one or more illumination sources and sensors. Illumination may be delivered to specific locations of a specimen holder, and returned illumination may be delivered to specific locations of a sensor array. Illumination may first pass a specimen, and a mirror or reflector may then return the illumination past the specimen. Optical splitters may be employed to couple pairs of fiber optics proximate a specimen holder. Such channels may further include a plurality of illumination sources positioned on one side of a specimen holder and a plurality of sensors on the other side. The plurality of sensor may capture image of a specimen and a spectrophotometer may concurrently scan the specimen. A plurality of specimens may be imaged and scanned in a single pass of a plurality of passes. Spherical or ball lenses may be placed in an optical path of the illumination to achieve a desired illumination pattern.

    Abstract: Devices, methods and systems for making optical measurements of a fluid at elevated pressures and temperatures are disclosed. A cell is designed for the optical spectroscopic measurements of fluids or gas using light from ultra violet (UV) to far infrared wavelengths, among other wavelengths. A cell is described that is well suited for applications using very small fluid volumes, on the order of micro liters, such as microfluidic systems. Some described embodiments are suited for very high pressure and temperature environments (for example, 20kpsi or greater at 175 degree C or greater). Such conditions, for example, may be found in oilfield downhole environments. Some embodiments provide are inexpensive, and make use of replaceable lenses that are used as a pressure barrier and for collimation of the optical beam path for spectroscopic measurements.
