Abstract
A detection system includes a modulator to apply a circular polarization modulation to an incident beam of radiation, a sample holder through which the modulated beam is pass, a grating to diffract the beam of radiation, an array of solid state detectors arranged to receive different wavelengths of the beam, and a process arranged to synchronise detected signals with the modulation applied by the modulator, in order to measure the spectral circular dichroism of the sample.
