    Abstract: An imaging apparatus comprises a first optical fiber configured to deliver a source beam of light generated by a light source and a polarizing beam splitter configured to polarize the source beam of light and direct diffusely reflected light toward a collection fiber optically coupled to an optical detector. The imaging apparatus also comprises a mirror configured to reflect the polarized beam of light onto the lens and direct reflected light away from a lens. The lens is configured to focus the polarized source beam of light onto an area of sample material and focus diffusely reflected light from the sample material into a reflection beam. The imaging apparatus also comprises a plano-convex curvature matching window disposed at a focal plane of the lens, wherein a convex surface of the curvature matching window is substantially matched to the focal plane curvature of the imaging lens.

    Abstract: An optical system for use in material processing includes a plurality of semiconductor diodes coupled to a beam combiner to generate a multiplexed optical beam. A cladding pumped fiber amplifier or laser receives the multiplexed optical beam and forms an intermediate beam having at least a first wavelength. An optical element receives the intermediate beam and forms an output beam with an output beam wavelength, wherein the output beam wavelength is at least in part longer than the first wavelength. A subsystem includes lenses or mirrors to deliver a delivered portion of the output beam to a sample. The delivered output beam has a temporal duration greater than about 30 picoseconds, a repetition rate between continuous wave and Megahertz or higher, and a time averaged intensity of less than approximately 50 MW/cm2. The output beam has a time averaged output power of 20 mW or more.

    Abstract: Wavelength information indicating a correspondence relationship between a plurality of light receiving elements of a light receiving unit and wavelengths of pieces of lights is stored. First and second intensity distributions of the light related to first and second dispersion images are acquired based on a signal outputted from each of the light receiving elements when a monochromatic light is passed through a opening of a light shielding body and first and second dispersion images related to primary and secondary diffracted light are formed on the light receiving unit. An estimated intensity distribution of the light related to the second dispersion image is calculated from the first intensity distribution according to a predetermined relational expression. A change amount related to the wavelength information is calculated based on the estimated intensity distribution and the second intensity distribution. The wavelength information is corrected according to the change amount.

    Abstract: A container for holding a sample and a system and method for a handheld spectrometer using the container is disclosed. In one embodiment, the container includes a vial with an optical window at the base of the vial. A sample may be placed in the vial. A hollow plunger may be slidably inserted into the vial which seals the gap between the plunger and the walls of the vial. The plunger includes a filter element. When the plunger is inserted into the vial, the sample is forced against the optical window and the filter element vents liquid and/or gas that is in the vial into the hollow plunger. A portable or handheld system for detecting, for example, biothreat agents makes use of the container in order to determine a spectrum of the sample. The optical window of the container is preferably substantially transparent to photons illuminating the sample and to photons produced due to the interaction of the illuminating photons and the sample.

    Abstract: An illumination device for a spectral optical measurement device includes arranged with respect to an optical axis of the illumination device which, during a measurement operation, extends along a normal to a center point of an area of a sample to be illuminated. One or more segments of a mirror in a shape of a ring are centered on the optical axis. The mirror has an internal reflective surface arranged such that, during the measurement operation, the internal reflective surface receives light emitted from the light source and reflects the light over the area of the sample to be illuminated. The internal reflective surface has a freeform shape in a cross-section through the internal reflective surface in a plane parallel to the optical axis (for example in which the optical axis lies), and, in a cross-section of the mirror in a plane perpendicular to the optical axis, the internal reflective surface is represented by a straight line.
