Abstract: A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

Abstract: A processing unit obtains a first spectrum detected in a first detection area and a first signal intensity detected in a second detection area after the light entering the housing is cut off, and then calculates a first correction spectrum by subtracting a first correction value calculated based on the first signal intensity from each component value of the first spectrum. The processing unit obtains a second spectrum detected in the first detection area and a second signal intensity detected in the second detection area while a cut-off portion is opened, and then calculates a second correction spectrum by subtracting a second correction value calculated based on the second signal intensity from each component value of the second spectrum. The processing unit calculates an output spectrum representing a measurement result by subtracting a corresponding component value of the first correction spectrum from each component value of the second correction spectrum.

Abstract: A method of Raman detection for a portable, integrated spectrometer instrument includes directing Raman scattered photons by a sample to an avalanche photodiode (APD), the APD configured to generate an output signal responsive to the intensity of the Raman scattered photons incident thereon. The output signal of the APD is amplified and passed through a discriminator so as to reject at least one or more of amplifier noise and dark noise. A number of discrete output pulses within a set operational range of the discriminator is counted so as to determine a number of photons detected by the APD.
