    Abstract: A spectrometer comprises a package having a stem and a cap, an optical unit arranged on the stem, and a lead pin penetrating through the stem. The optical unit has a dispersive part for dispersing and reflecting light entering from a light entrance part of the cap, a light detection element for detecting the light dispersed and reflected by the dispersive part, a support for supporting the light detection element such as to form a space between the dispersive part and the light detection element, a projection projecting from the support, and a wiring electrically connected to the light detection element. The projection is arranged at such a position as to be in contact with the stem. The lead pin is electrically connected to a second terminal part of the wiring arranged in the projection.

    Abstract: A spectrometer is provided, the spectrometer having an interferometer generating an interferogram by splitting an interferometer input signal between a reference arm and a variable delay arm, and introducing a delay between the split interferometer input signals prior to interfering the split interferometer input signals. The spectrometer additionally has a controllable delay element operable to adjust the delay introduced by the interferometer and a dispersive element outputting a plurality of narrowband outputs representative of a received broadband input signal. The interferometer and dispersive element are optically connected to output a plurality of narrowband interferograms representative of a spectra of a spectrometer input signal received by the spectrometer, and the plurality of narrowband interferograms are received by a detector array for analysis.

    Abstract: Provided is a spectroscopic detector including: a light source for generating polychromatic light 11; a single diffraction grating 13; an excitation optical system for guiding the light from the light source 11 onto the diffraction grating 13, for selecting one wavelength from the light diffracted by the diffraction grating 13, and for casting the selected wavelength of light into a sample as excitation light; a detection optical system for guiding observation light emitted from the sample irradiated with the excitation light onto the diffraction grating 13 to disperse the observation light; and a photodetector 15 for detecting the observation light dispersed by the detection optical system. By using one diffraction grating 13 in both the excitation optical system and the detection optical system, the number of diffraction gratings is reduced, whereby both the cost reduction and the downsizing of the device are achieved.

    Abstract: A system and method for spectroscopic mapping, with configurable spatial resolution, of an object include a fiber optic bundle having a plurality of optical fibers arranged in a first array at an input end with each of the plurality of optical fibers spaced one from another and arranged in at least one linear array at an output end. A first mask defining a plurality of apertures equal to or greater in number than the plurality of optical fibers is positioned between an object to be imaged and the input end of the fiber optic bundle. An imaging spectrometer is positioned to receive light from the output end of the fiber optic bundle and to generate spectra of the object. A sensor associated with the imaging spectrometer converts the spectra to electrical output signals for processing by an associated computer.
