摘要: A spectroscopy system having enhanced noise reduction that comprises (i) an arc lamp light source (20) of emitted light, which is projected as image (A') the source; (ii) a slit aperture (22) trough projected; and (iii) detector (23) operably associated with for detecting light. The (22), (20), each have major axis. axis oriented essentially orthogonally to (A'), so signal-to-noise ratio improved compared when parallel lamp.
