摘要： Raman signal amplification apparatus comprises an ellipsoidal reflector providing a first real focus f1, and second real or virtual focus f2, both foci being situated within a sample volume. When an input laser excitation beam having an initial numerical aperture (NA) is focused onto one of the foci, the beam is reflected by the reflector and refocused onto alternating foci, such that the NA of the reflected optical path progressively increases for higher efficiency collection of Raman emissions from the multiple foci. The ellipsoidal reflector may be a half section providing a single real focus f1, with a flat reflector producing a mirror image of the ellipsoidal reflector, such that f2 is a virtual focus occupying the same point as f1. Alternatively, the ellipsoidal reflector may have a first half section with a first real focus f1 and a second half section with a second real focus f2.

摘要： A method and apparatus for encapsulating optical elements, particularly dichromated gelatin (DGC) holographic optical elements (HOEs), exhibits a very high degree of environmental integrity. In broad terms, the optical element is disposed between opposing plates, and a metal seal soldered to the edge(s) of the plates to seal the optical element therewithin.

摘要： Raman measurement apparatus optimized for gaseous and other low-concentration samples includes a focusing objective that uses only first-surface mirrors instead of lenses, thereby dramatically reducing background noise. In the preferred embodiment, the focusing and collimation functions performed by the objective section are performed by an off-axis parabolic mirror. A spherical first-surface mirror opposing the parabolic mirror re-images the counter-propagating beam back through the same focus for re-collimation by the parabolic mirror. A probe-head section operative to generate the counter-propagating beam has substrates and surfaces arranged such that the excitation beam does not pass through any substrates after it is filtered by the bandpass coating, thereby further decreasing background signals. Additionally, when the objective section includes the opposing spherical mirror, the excitation beam is collected substantially in its entirety and neutralized out of the collection path by the probe-head section.

摘要： A multi-channel, reconfigurable fiber-coupled Raman instrument uses fiber optic switches for laser and calibration light routing to facilitate automated calibration, diagnosis and operational safety. The system allows wavelength axis calibration on all channels; laser wavelength calibration (including multiple and/or backup laser options); fiber coupling optimization; fault detection/diagnosis; and CCD camera binning setup. In the preferred embodiment, dedicated calibration channels surround data channels on a 2-dimensional CCD dispersed slit image implemented using a unique cabling architecture. This “over/under” calibration interpolation approach facilitates quasi-simultaneous or sequential calibration/data acquisitions. CCD binning between sequential calibration and data acquisitions enables higher density multi-channel operation with tilted images based upon a multiplexed grating configuration. A diamond sample is used as a Raman shift reference for laser calibration, preferably in the form of a small disc sampled with an edge-illuminating probe using two unfiltered fibers.

摘要： Disclosed is a method of positioning a focused image within a sampled medium in an optical measurement probe of the type wherein a focused sampling image is transmitted through a window having a surface facing a sampled medium. A test medium is measured, preferably through the window, and the magnitude of an optical signal associated with the test medium is then compared to the magnitude of an optical signal associated with the window, and the result of the comparison is used to position the focused image. Typically, the magnitudes of optical signals are representative or Raman scattering or another wavelength-selective radiative sampling process such as fluorescence detection. The method is not limited in terms of window composition, and is compatible with sapphire windows commonly used in industry. Nor is the invention limited in terms of test medium though, in the preferred embodiment a fluid hydrocarbon such as isopropyl alcohol is used.

摘要： Various optical probe configurations are particularly suited to the monitoring of a process flow through the wall of a containment vessel. A probe body extends through, and is sealed to, the wall of the containment vessel. The probe body has an inner wall terminating in a distal end with a window, enabling light from the process flow to pass therethrough and into the probe body. In one embodiment, one or more lenses are disposed within the probe body to focus the light into a focal point, and a restriction of the inner wall of the probe body is used to create a narrow aperture at the focal point. In an alternative embodiment, a plug transparent to the light of interest is sealed to the inner wall of the probe body. As a further alternative, the elements include a second window creating a cavity with the distal window, and a port into the cavity accessible from outside the window for sampling purposes. Although these embodiments are referred to as ‘alternative,’ they may be used in combination as well as separately. Indeed, all three embodiments may be used simultaneously for increased integrity. In addition, although the probe body is presumed to carry light in both directions for excitation and collection, invention is not limited in this regard or the way in which light is carried to, or from, the body itself. That is, a probe according to the invention may be used only for excitation or collection, and optical fibers may, or may not, be used between the body and a source or radiation and/or analysis means.

摘要： Calibration wavelengths are injected into an optical detection system preferably at a point after laser rejection filtration, enabling the known spectral content of the calibration radiation to pass through and into a spectrograph. In a preferred embodiment, at least some of the wavelengths used for calibration are derived through the excitation of a noble gas such as neon, thereby conveniently and economically providing a full-spectrum calibration line set. The feed from the laser source used to illuminate the sample is also preferably introduced into the collection path, enabling both the calibration wavelengths and laser line to be detected and used in calibration. The invention is applicable to spectral analysis systems in general, including non-Raman systems and systems which do not require a laser notch pre-filter stage.

摘要： An optical probe assembly, which may be used with or without optical fibers for remote operation, incorporates a leak-detecting capability. A source such as a laser is used for optically exciting at least a portion of a sample substance, causing wavelengths characteristic of the sample to be emitted along a collection path for reception by spectral analysis means. The same laser or a different source is employed for optically exciting a point within a test region, causing wavelengths characteristic of any substances contained or entering into the test region to merge with those of the sample within the collection path.

A confocal aperture is supported in intimate proximity with respect to the first end of the fiber, preferably within two core diameters from the first end of the fiber.
