Abstract: An encoder spectrograph is used to analyze radiation from one or more samples in various configurations. The radiation is analyzed by spatially modulating the radiation after it has been dispersed by wavelength or imaged along a line. Dual encoder spectrographs may be used to encode radiation using a single modulator. An encoder spectrograph may be used wherein the first optics comprises a diffraction grating that is optimized for an annular-shaped intercept between the dispersed image and the radiation filters on a modulator.

Abstract: In a multi-wavelength spectroscopic apparatus using diffraction gratings, a first diffraction grating is a diffraction grating with diffraction efficiencies of p-polarized light and s-polarized light being equal on a short wavelength side of an operating wavelength range, and a second diffraction grating is a diffraction grating with diffraction efficiencies of p-polarized light and s-polarized light being equal on a long wavelength side of an operating wavelength range. By performing dispersion with two such diffraction gratings, it is possible to enlarge the amount of angular dispersion, and to produce a spectroscopic apparatus, which cancels wavelength dependencies of the diffraction efficiencies and has a small wavelength dependency of the diffraction efficiency.

Abstract: A spectrometer is designed capable of effectively covering the full desired spectral range using an array of multiple diffraction gratings arranged in gradually differentiated angles to diffract certain sub-range of photon wavelengths to the target detectors without relying on mechanically changing gratings or use of any moving parts. The optically subdivided spectral analysis results are then electronically integrated to accurately yield the desired full range spectral measurement at a speed compatible to the limit of optical and digital analyzers' speed of the measuring system without manual adjustment and/or mechanical movement delays.

In an alternative embodiment, both an infrared spectrometer and a Raman spectrometer are included in a single instrument and a common infrared light source is used by both spectrometers. In another embodiment, a vibrational spectrometer and a stoichiometric spectrometer are combined in a single instrument and are coupled to exchange respective spectral information of the target material and to compare the spectral information against a library of spectra to generate a real-time signal if a selected component is present in the target material.

Abstract: A system for authenticating sampled objects including a database, a plurality of spectrum measuring devices, and a plurality of computers. The database stores a plurality of reference patterns measured from known reference objects. Each of the spectrum measuring devices measures a region of respective sampled objects so as to produce spectral content information identifying the sampled objects. The spectral content information includes information indicative of colors inside the visible spectrum of the human eye. The computers have access to spatial analysis software. The computer receives the spectral content information identifying the sampled object and provides the spectral content information to the spatial analysis software to generate a unique measured pattern. The spatial analysis software compares the unique measured pattern with the reference patterns stored in the database, and outputs signals indicative of matches between the unique measured pattern with the reference pattern within a tolerance level whereby the colors of the regions of the sampled objects are utilized to authenticate the sampled objects.

Abstract: A spectroscope comprises an incident slit 12, a collimator lens type optical system 14 that makes the light rays having passed through the incident slit 12 parallel light rays, a reflection type diffraction grating 16 that receives the parallel light rays and, according to the wavelength, outputs these light rays at different angles, a condenser lens type optical system 14 that condenses the output light from the diffraction grating 16, and two-dimensional detector 16 having a two-dimensional light-receiving surface that detects the light rays that have been condensed by the condenser lens type optical system. The collimator lens type optical system and the condenser lens type optical system are disposed so that the angle 2γ defined between the optical axis of the collimator lens type optical system and the optical axis of the condenser lens type optical system may be acute. The condenser lens type optical system is disposed so that the distance between itself and the diffraction grating may be shorter than the distance between the collimator lens type optical system and the diffraction grating. A normal line vector at the central portion of the reflection surface of the diffraction grating may be directed, from a bisector of the angle defined between the optical axis of the collimator lens type optical system and the optical axis of the condenser lens type optical system, toward a side where the collimator lens type optical system is disposed.
