    Abstract: A spectrometer system includes a thermal light source for illuminating a sample, where the thermal light source includes a filament that emits light when heated. The system additionally includes a spectrograph for measuring a light spectrum from the sample and an electrical circuit for supplying electrical current to the filament to heat the filament and for controlling a resistance of the filament. The electrical circuit includes a power supply that supplies current to the filament, first electrical components that sense a current through the filament, second electrical components that sense a voltage drop across the filament, third electrical components that compare a ratio of the sensed voltage drop and the sensed current with a predetermined value, and fourth electrical components that control the current through the filament or the voltage drop across the filament to cause the ratio to equal substantially the predetermined value.

    Abstract: Spectrophotometric apparatus and methodology suitable for continuous and long-term use. The apparatus includes a monochromator (13) providing pre-dispersed monochromatic light to the optical inputs of a pair of fiber optic cables (34-37) and a translator (43) for alternatively positioning the fiber optic cables (34-37) at the same location with respect to the monochromator output. One of the cables (61) conducts light to a sample under study while the other cable (35b) provides a reference for light intensity measurements. The methodology includes the steps of performing two scans through the monochromator output for each measurement on the sample. The fiber optic cables are moved between scans so that the cable employed in the latter scan occupies the former position of the cable employed in prior scan.
