Abstract:
1. A fluorescence spectrophotometer system comprising: a light source; a first double monochromator comprising two or more gratings and operative to separate light from the light source into a plurality of wavelengths and to output selected wavelengths as excitation light; a light transfer module comprising a first reflection surface and a second reflection surface, the first and second reflection surfaces substantially centered on a common axis, wherein: a second double monochromator comprising two or more gratings and operative to separate the fluorescent or luminescent light directed by the light transfer module into a plurality of wavelengths and to output selected wavelengths of the fluorescent or luminescent light as emission light; and a photodetector and analyzer, operative to receive the emission light output by the second double monochromator, to detect the selected wavelengths of the emission light, and to output an indication of the selected wavelengths.
