Abstract
A dispersive optical spectrometer is disclosed which comprises light detection means, dispersion means for separating light radiation into spectral components and for directing the spectral components toward the light detection means, means for admitting light radiation into the entrance focal plane and for directing the light radiation toward the dispersion means, the light radiation admitting means including a plurality of spaced-apart apertures, and light transmission means for transmitting light radiation from a light source to one or more of the apertures. In a preferred embodiment, the apertures form a two-dimensional, rectilinear array for producing non-overlapping spectra.
