      abstract     = {Optical micro-spectroscopy is an invaluable tool for
                      studying and characterizing samples ranging from classical
                      semiconductors to low-dimensional materials and
                      heterostructures. To date, most implementations are based on
                      point-scanning techniques, which are flexible and reliable,
                      but slow. Here, we describe a setup for highly parallel
                      acquisition of hyperspectral reflection and
                      photoluminescence microscope images using a push-broom
                      technique. Spatial as well as spectral distortions are
                      characterized and their digital corrections are presented.
                      We demonstrate close-to diffraction-limited spatial imaging
                      performance and a spectral resolution limited by the
                      spectrograph. The capabilities of the setup are demonstrated
                      by recording a hyperspectral photoluminescence map of a
                      CVD-grown MoSe$_2$-WSe$_2$ lateral heterostructure, from
                      which we extract the luminescence energies, intensities and
                      peak widths across the interface.},
