An optical spectrometer comprising:
- an aperture;
- a collimator;
- an Echelle grating;
- an off-axis Schmidt telescope;
- and
- a detector,
- wherein the collimator is optically coupled to the aperture and the Echelle grating,
- wherein the off-axis Schmidt telescope is optically coupled to the Echelle grating, and the detector,
- wherein light entering the spectrometer through the aperture is directed to the detector, and
- wherein light incident on the detector comprises a plurality of wavelengths that are spatially separated across the ultraviolet light spectrum and the visible light spectrum.
