Paper Abstract

Image slicing integral field units were developed to provide spatially resolved spectroscopy over a two dimensional field of view. Spectral slicing applies similar design principles to provide an alternative to cross-dispersion. Key benefits include more efficient use of detector space and greater flexibility in selecting the wavelength ranges within each band. We will describe the design of a deployable spectral slicing mode as part of the METIS LM-band high resolution spectrometer.
