An optical fiber polychromator for separating light radiation into spectral bands which can be simultaneously displayed in a stacked, two-dimensional non-overlapping arrangement. Light radiation is directed through entrance slits into a Rowland Circle spectrometer apparatus by optical fibers which are arranged at discrete locations on an entrance focal plane. The radiation is separated into spectral windows or bands which are focused in parallel onto the target of a vidicon detector. The discrete entrance locations are defined in accordance with column and row coordinates of a matrix in the entrance focal plane wherein the column and row coordinates are separated by predetermined distances dependent upon the dimensions of the detector target and the entrance slits. The entrance locations are arranged so that no two locations have the same row or column coordinate whereby the desired parallel, non-overlapping distribution of spectral bands is achieved.
