Hyperspectral imaging apparatus

A spectrometer module for a hyperspectral imaging apparatus, the spectrometer module comprising:

• an emission light signal entrance for receiving a line laser scan emission light signal from a fore-optics module;
• and
• a plurality of optical components forming a folded optical path between the emission light signal entrance and a deflection mirror, the plurality of optical components including the deflection mirror and a diffraction element being arranged in an optical plane, the deflection mirror arranged to deflect a diffracted light signal out of the optical plane into a detector positioned above or below the optical plane.

A fore-optics module for a hyperspectral imaging apparatus, the fore-optics module comprising:

• a line laser arranged to emit scanning line light along a scanning light signal pathway towards a sample holder, the sample holder arranged to hold or support a sample;
• and
• a dichroic filter positioned in the scanning light signal pathway and arranged to allow the scanning line light to pass through it to the sample holder, the dichroic filter deflecting a line scan emission light signal reflected from the sample out of the scanning light signal pathway onto an emission light signal pathway towards a spectrometer module such that the emission light signal travels over a portion of the scanning light signal pathway prior to being deflected by the dichroic filter.
