Classification: CPC A  G | IPC A  G

Claim 0:
1. A spectrometer for analysing the spectra of a plurality of polarised light beams, said spectrometer comprising:
a polarisation beam splitter for directing optical power according to polarisation state;
a wavelength dispersive element for dispersing a plurality of polarised light beams;
a reflective polarisation state transformer for transforming the polarisation of said plurality of polarised light beams; and
a two-dimensional sensor array for recording the spectra of said plurality of polarised light beams, wherein said spectrometer is configured such that, in use, said polarisation beam splitter directs incoming polarised light beams to said wavelength dispersive element and said reflective polarisation state transformer and directs the dispersed polarisation transformed light beams to said two-dimensional sensor array.
