Abstract: A spectrometer which in one embodiment including a dispersive element and a concave element. The dispersive element may be a flat or concave grating which receives light and reflects the light in different collimated wavelengths. The concave element being located downstream from the dispersive element and arranged to reflect and focus the light toward a detector. The reflected light from the concave element including astigmatism. A cylindrical lens positioned between the concave element and the detector and configured to simultaneously correct the astigmatism and demagnify the light across the detector. In one embodiment the cylindrical lens varies in thickness progressively along its length.

Abstract: A method for identification of a material by analysis of a sample of the material is disclosed. The method comprises illuminating the sample with a plurality of excitation wavelengths, measuring a plurality of emission wavelengths for each excitation wavelengths to define a measured three-dimensional intensity contour. The values of maxima are located in the three-dimensional intensity contour and are compared to a library of values of known maxima associated with known species. A model of a three-dimensional intensity contour is generated and compared to the measured three-dimensional contour to determine residual errors. A comparison of errors between the generated and measured three-dimensional contours. Error minimization is used to determine the correct model of the three dimensional intensity contour.
