Abstract: An optical system for a multidetector array spectrophotometer includes multiple light sources (10,12) for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits (40,42) of a multi-slit spectrograph for multiple wavelength range detection. The spectrograph has two or more slits (40,42) which direct the selected wavelength ranges of the light spectra to fall upon a dispersive and focusing system which collects light from each slit, disperses the light by wavelength and refocuses the light at the positions of a single set of detectors (46).
