摘要： 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.

摘要： 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.

摘要： Raman emissions from a sample may be enhanced by using a microsphere to confine the impinging radiation into a photonic nanojet and thereby increase the intensity of the radiation that is striking the sample. The amount of enhancement may be improved by configuring the diameter and refractive index of the microspheres in conjunction with the dispersion and the wavelength of the radiation to increase the intensity of the beam of radiation in the photonic nanojet.

摘要： An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

摘要： A sensing apparatus for detecting light of first and second fluorescent wavelength bands has a light source to generate an excitation wavelength to a first collimator element. A dichroic multiplexer has a first coated surface oblique to the optical axis and treated to transmit the excitation wavelength and to reflect the second fluorescent wavelength band and a second coated surface treated to transmit the excitation wavelength and the second fluorescent wavelength band and to reflect the first fluorescent wavelength band. A focusing element focuses the excitation light toward a light guide and directs collimated light of the first and second fluorescent wavelength bands from the light guide to the dichroic multiplexer. A first detector element is in the path of reflected light of the first fluorescent wavelength band and a second detector element is in the path of reflected light of the second fluorescent wavelength band.

摘要： 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, 20 kpsi 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.
