Abstract

An analysis system has a sample region (1), a source of excitation radiation (3), and a wavelength-nonspecific beam splitter (13) to deliver excitation radiation to a sample. A dispersion element (23) disperses returned radiation from the sample to be analysed that has been transmitted by the beam splitter. A selectively switchable micromirror devic (35) received returned radiation that has been dispersed by the dispersion element. A detector (43) detects radiation that is received from the switchable micromirror device. The switchable micromirror device removes at least a majo part of residual excitation radiation from the returned radiation that is passed to the detector. A method of quantifyi target analyte(s) in a sample includes receiving radiation from a sample region for each of a plurality of points along least part of the length of the sample region, and delivering at least some of the radiation to the detector.
