    Abstract: Apparatuses and methods for performing spectroscopy and optical microscopy are disclosed. In at least one embodiment, a Raman spectrometer includes a vacuum ultraviolet light source configured to generate light having a wavelength within a window in the vacuum ultraviolet region of the electromagnetic spectrum within which a local minimum in the absorption coefficient of Oxygen occurs. The spectrometer also includes a lens device that receives a first portion of the generated light, directs at least some of the first portion of the generated light toward a target location, receives reflected light from the target location, and directs the reflected light toward a further location. The spectrometer further includes a dispersive device that receives at least some of the reflected light and outputs dispersed light produced based thereupon, and a camera module that is positioned at additional location, where the camera module receives at least some of the dispersed light.

    Abstract: For investigating the spectrum of emission radiation excited in an object by incident radiation, miniaturised spectrometers are known for mobile use. These devices comprise a light source with perforated shutter, an illuminating beam path, a detecting beam path and a spectrometer.For the miniaturised spectrometer according to the invention, a diode laser is preferably used as an edge emitter (without a perforated shutter). The window of the edge emitter is arranged at the focal point of the converging lens at the input of the illuminating beam path (without an optical fibre), preferably without a perforated shutter. The edge emitter produces a divergent beam pencil with an elliptical cross-section. The length ratio of the main axes of the ellipse is more than 2:1. The large main axis of the ellipse runs parallel to the longitudinal axis of the entry slit of the microspectrometer.The miniaturised spectrometer has a reduced size and an increased sensitivity for emission radiation of low intensity. The excitation radiation subjects the object to little loading. Objects in the micro litre or milligram range can be investigated under gentle conditions.

    Abstract: A downhole fluid sample container includes a fluid sample container detachably coupled to a downhole sub, the fluid sample container having an internal chamber for receiving the downhole fluid. At least one semimetal (for example, silicon or germanium) window is coupled to the fluid sample container, the window being substantially transparent to electromagnetic energy wavelengths within a selected band. A method includes transmitting electromagnetic energy from an electromagnetic energy source to downhole fluid through at least one semimetal window in a container, receiving an electromagnetic energy response with a spectrometer, and estimating the downhole fluid property based at least in part on the electromagnetic energy response.

    Abstract: A method for the formation of surface enhanced Raman scattering substrates. The method produces thin substrates that have a nanoparticle ink deposited thereon. The nanoparticle ink may be any suitable nanoparticle ink such as silver, gold or copper nanoparticle ink which includes stabilized nanoparticles. The substrates and nanoparticle ink undergo a first step of heating in order to remove liquid vehicle from the ink. The substrates and nanoparticles then undergo a second step of heating for an amount of time sufficient to remove a substantial portion of the stabilizer and provide a fractal aggregate nanoparticle layer on the substrate having a certain resistivity or conductivity suitable for Raman scattering. This creates SERS substrates with enhanced amplification properties.
