A compact photoluminescence hyperspectral imaging apparatus comprises a fore-optics module and a spectrometer module. The fore-optics module has a line laser for line scanning a sample. The fore-optics module comprises optical components forming an emission light signal pathway to guide a line scan emission light signal from the sample into the spectrometer module. The spectrometer module comprises a plurality of optical components forming a folded optical light signal pathway between an emission light signal entrance and a deflection mirror. The plurality of optical components including a diffraction element and the deflection mirror are arranged in a single optical plane. The deflection mirror is arranged to deflect a diffracted light signal from the diffraction element out of the optical plane into a detector positioned above or below the optical plane.
