DISPERSION SPECTROMETER

DISPERSION SPECTROMETER

A dispersion spectrometer (2) comprises a wavelength dispersive element (12) located within a path (14) of incoming radiant energy; and a first detector (16) disposed to detect incoming radiant energy dispersed by the dispersive element (12). The spectrometer (2) further comprises a second detector...

Beschreibung
Zusammenfassung:A dispersion spectrometer (2) comprises a wavelength dispersive element (12) located within a path (14) of incoming radiant energy; and a first detector (16) disposed to detect incoming radiant energy dispersed by the dispersive element (12). The spectrometer (2) further comprises a second detector (18) disposed to register the intensity of at least a portion of the un-dispersed incoming radiation and configured to generate a signal representative of the registered intensity, the first detector (16) being adapted to have operational parameters in the form of integration time and/or sensitivity gain varied in response to the signal.
