Abstract: Innovative techniques that result in a better signal-to-noise ratio for spectrographic analysis of substances in a target than conventional techniques. In these techniques, light illuminates a target with at least some of the light penetrating the target. At least a portion of the light that penetrates the target is collected from a region on the target's surface that is not directly illuminated. Preferably, at least a majority of the collected light is light that penetrates the target. Also preferably, the light that illuminates the target is in a pattern that partially but not completely surrounds the region from which the portion of the light that penetrates the target is collected. A spectrum of at least a portion of the collected light is analyzed.

Abstract: A shutter assembly for use with a spectrometer having at least one source of optical radiation such as at least one laser capable of generating an excitation light beam having an illumination path. The shutter assembly includes a shutter having at least one of (i) at least one calibration material capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer and (ii) a mirror capable of diverting at least one of the illumination path and a collection path relative to a calibration standard capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer. The shutter assembly further includes a mechanism capable of moving the shutter into at least a first position in the path of the light beam and a second position out of the path of the light beam to enable a sample to be analyzed.
