Abstract
An improved spectrophotometer, especially suitable for use in centrifugal analysis instrumentation, is disclosed. The spectrophotometer is improved by including therein a detector comprising a photodiode array assembly having a photodiode array, a spectral filter assembly situated substantially parallel thereto and in the path of incident light and means for attenuating stray light which would otherwise impinge on each of the photodiodes of the array.
