Abstract
An optical system for a multidetector array spectrophotometer which includes multiple light sources for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits of a multi-slit spectrogrpah for multiple wavelength range detection. The spectrograph has two or more slits 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.
