    Abstract: An spectrometer including Raman and LIBS spectroscopy capabilities is disclosed. The spectrometer includes a laser source configurable to produce a lased light directable towards a target substance, the laser source having a single wavelength and having sufficient power to cause a portion of the target to emit Raman scattering and sufficient to ablate a portion of the target substance to produce a plasma plume. A separate remote light collector is optically configurable to collect light emitted from the portion of the target emitting Raman scattering and from the portion of the target producing the plasma plume. A filter is optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light, and a spectroscope is optically coupled to the filter and configured to separate the collected and filtered light into a frequency spectrum comprising a Raman spectrum and a laser-induced breakdown spectrum. Finally, an electronic light sensor is used to record the frequency spectrum.

Under processor control, the optical characteristics measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence, gloss and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention. A method of producing dental prostheses based on measured data also is disclosed.

    Abstract: The invention disclosed here teaches methods to fabricate and utilize a non-dispersive holographic wavelength blocker. The invention enables the observation of the Raman signal near the excitation wavelength (˜9 cm−1) with the compactness of standard thin film/holographic notch filter. The novelty is contacting several individual volume holographic blocking notch filter (VHBF) to form one high optical density blocking filter without creating spurious multiple diffractions that degrade the filter performance. Such ultra-narrow-band VHBF can be used in existing compact Raman instruments and thus will help bring high-end research to a greater number of users at a lower cost.

    Abstract: 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.
