Abstract: A centrifuge sample is optically scanned during centrifuging. The sample, placed in a centrifuge rotor having a cell with top and bottom windows, is spun until stratification and discrete layering occurs within the sample. Such layering occurs on layers that are precisely normal to the radius of the centrifuge at the point of sample and parallel to the spin axis of the centrifuge. A slit scanner having a slit normal to the sample plane transverses the width of the sample below the cell to detect with precision the precise location of the strata in the cell. A light source is reflected by a toroidal mirror having two radius of curvature. One radius of curvature is selected to collimate rays of light parallel to the layer of the sample. The mirror is ruled with respect to the other radius of curvature to chromatically classify light to preselect band width. Rotation of the mirror preserved collimation but enables selected scanning light frequency.

Abstract: The invention relates to a spectrometer having a plurality of dispersive optical elements arranged such that electromagnetic radiation entering into the spectrometer is incident on the dispersive optical elements to be split spectrally there; the dispersive optical elements differ from one another with respect to their spatial positions and/or their spectral splitting capabilities; the dispersive optical elements are arranged such that the spectra generated by the respective dispersive optical elements by the splitting of the electromagnetic radiation extend in the same direction and are adjacent to one another transversely to this direction of the spectral splitting; and a detector resolving spatially in two dimensions and being located in the optical path of the split electromagnetic radiation for the detection of at least some respective part sections of the spectra. The invention furthermore relates to an analysis apparatus for determining absorption properties of solid, liquid or gaseous substances or substance mixtures.

Abstract: A spectrometer includes a support having a bottom wall part in which a depression is provided and a side wall part, a light detection element supported by the side wall part while opposing the depression, a resin layer disposed at least on an inner surface of the depression, and a dispersive part provided in the resin layer on the inner surface of the depression. The resin layer is in contact with an inner surface of the side wall part. A thickness of the resin layer in a first direction in which the depression and the light detection element oppose each other is larger in a part in contact with the inner surface of the side wall part than in a part disposed on the inner surface of the depression.
