Abstract: In a spectrometer, preferably in a spectrometric microscope, input light is provided from a light source to a specimen via a source objective element (e.g., a Schwarzchild objective), and the aperture of the light source is matched to the aperture of the source objective element to maximize light throughput to the specimen. The light from the specimen is then collected at a collector objective element and delivered to a camera element, which in turn provides the light to a photosensitive detector. The apertures of the camera element and the collector objective element are also matched to maximize light throughput from the specimen to the detector. As a result, light loss from vignetting effects is reduced, improving the intensity and uniformity of illumination and the sensitivity and accuracy of spectral measurements.

Abstract: The disclosure relates generally to methods and apparatus for using a fiber array spectral translator-based ('FAST') spectroscopic system for performing spectral unmixing of a mixture containing multiple polymorphs. In an embodiment, a first spectrum of a mixture containing polymorphs of a compound is obtained using a photon detector and a fiber array spectral translator having plural fibers. A set of second spectra is provided where each spectrum of the set of second spectra may be representative of a different polymorph of the compound. The first spectrum and the set of second spectra may be compared, and based on the comparison, the presence of one or more polymorphs in the mixture may be determined.

Abstract: Pulse laser light L transmitted through a laser light transmission optical fiber 16 to an optical system unit 13 passes through a distribution reflecting mirror 27 and is condensed by a condenser lens group 30. The condenser lens group 30 irradiates the condensed laser light onto an analysis object 12. The fluorescence F emitted as a result of the irradiation of the pulse laser light L onto the analysis object 12 is condensed by the condenser lens group 30 and is reflected by the distribution reflecting mirror 27. The optical system unit 13 transmits the fluorescence F reflected by the distribution reflecting mirror 27 through an fluorescence transmission optical fiber 17 to a fluorescence measuring instrument. The fluorescence measuring instrument determines the quantity of elements included in the analysis object 12 on the basis of the fluorescence F.

Abstract: The invention relates to an assembly for identifying coatings (3; 14) lying on the surface of components or objects (2) and for determining the chemical characteristics and the surface properties of said coatings (3; 14). The assembly comprises a light source (4) for illuminating the coating (3; 14) on the component surface that is to be analysed and means for projecting light from the light source (4) via the surface (3') of the coating (3; 14) that is to be analysed onto an entry slit (7). The light from the entry slit (7) is projected onto a two-dimensional detector unit (8) in a wavelength-dependent manner by means of a grating (10). An evaluation unit (11), which is electrically connected to the detector unit (8) evaluates and processes the signals emitted by the illuminated detector elements (9) of the detector unit (8).

Abstract: The invention concerns a achromatic and absorption reducing light collecting system, particularly adapted to optical spectrometric analysis. Said system collects light emitted by at least one light source (52) and focuses same on at least one light detecting device (54). It comprises preferably a first mirror (58) which collects light emitted by the source and focuses same on a second mirror (60) which in turn focuses it on the device. The system is equipped with a chamber which is opaque to any type of light, in particular to ultraviolet rays, and wherein are placed the light source, the light detecting device and the mirrors, and means for creating a vacuum in said chamber or for filling it with a gas which is transparent to ultraviolet rays.

Abstract: A zoom lens (40) is provided between a sample (2) and a slit (12) of a spectrophotometer to change the size of the image of the sample on the slit plane. A picture of the sample is taken by the zoom lens (40) and is shown on a display screen (33), on which a window is superimposed. When an operator changes the location of the window, the sample (2) is moved accordingly and, when the operator changes the size of the window, the focal length of the zoom lens (40) is changed, whereby the size of the measurement area is changed. By changing the size of the measurement area on the slit plane while the size of elementary photo-sensors of a photo-detector (17) is unchanged, the resolution of two-dimensional spectrophotometry can be changed.

Abstract: An optical relay having a pair of simple lenses and an opaque barrier defining an aperture. In a spectrometer, the optical relay is positioned between a light source and an opaque barrier defining a slit to focus light of a reference wavelength w r onto the slit. The location of the aperture and the choice of w r are selected so that the flux of light through the slit is substantially flat as a function of wavelength.

Abstract: A freeform surface imaging spectrometer system including a primary mirror, a secondary mirror, a tertiary mirror, and a detector is provided. The secondary mirror is a grating having a freeform surface shape, and the grating having the freeform surface shape is obtained by intersecting a set of equally spaced parallel planes with a freeform surface. A plurality of feature rays exiting from a light source is successively reflected by the primary mirror, the secondary mirror and the tertiary mirror to form an image on an image sensor. A reflective surface of each of the primary mirror, the tertiary mirror surface and the tertiary mirror is an xy polynomial freeform surface.
