    Abstract: Increased sensitivity of spectrometers through reducing noise in independent voltage signals via a differential voltage analyzer utilizing a reference wavelength from a wavelength region in which the optical absorption of the sample is negligible. In an embodiment, a grating permits selection of a reference wavelength. In another embodiment, filters permit selection of a reference wavelength. In yet another embodiment, both a grating and a filter permit selection of a reference wavelength. In an aspect, the differential voltage analyzer reduces noise by minimizing a differential voltage between the independent voltage signals and the reference voltage signal by adjusting the value of a cancellation coefficient.
