Abstract: 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.

Abstract: 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.

Abstract: Systems and methods that facilitate analysis of superficial tissue based at least in part on a depth-selective fiber optic probe are discussed herein. The depth-selective fiber optic probe can include an illumination fiber for providing light to the superficial tissue, a collection fiber for collected reflected light, a ball lens that couples the fibers, and a protective overtube that houses the ball lens and fibers. The distances between the ball lens and fibers and between the fibers can be optimized based on several factors, such as by minimizing the illumination spot size, maximizing the overlap between the illumination and collection spots, and based on the angle between the illumination and collection beams.

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, 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.

Abstract: Near-field Raman imaging is performed by holding a dielectric microsphere (e.g. of polystyrene) on or just above the surface of a sample in a Raman microscope. An illuminating laser beam is focused by the microsphere so as to produce a near-field interaction with the sample. Raman scattered light at shifted wavelengths is collected and analysed. The microsphere may be mounted on a cantilever of an atomic force microscope or other scanning probe microscope, which provides feedback to hold it in position relative to the sample surface. Alternatively, the microsphere may be held on the sample surface by an optical tweezer effect of the illuminating laser beam.
