Abstract: A simple and practical modification of a two-dimensional-imaging color filter spectrograph is presented. By the modification, the spatial displacement of images taken on different wavelengths was reduced below 10 micrometers in spite of miliradian wedges of the filters and beam pointing instability. The device allows precise two-dimensional measurement of beam dispersion and spectral beam profiles in semi-compact design.
