Abstract:
1. A hyperspectral imaging system comprising: a slit element; an optical sub-system having at least one refractive lens element; said optical sub-system substantially collimating, at a back plane, electromagnetic radiation emanating from said at least one slit element; at least one reflective dispersive element located substantially at the back plane; said at least one reflective dispersive element angularly separating substantially collimated electromagnetic radiation according to wavelength; said optical sub-system also imaging, at an image plane, dispersed electromagnetic radiation reflected from said at least one reflective dispersive element; and, at least one detecting element located substantially at the image plane; an orientation of the image plane being substantially identified by a line perpendicular to the image plane and located at an angle with respect to an optical axis of said optical sub-system; said optical sub-system being symmetrical about the optical axis; said at least one detecting element detecting the dispersed electromagnetic radiation reflected from said at least one reflective dispersive element.
