Abstract
A spectrometer comprising a collimating element for receiving input light and collimating the same, a dispersive optical element for receiving light from the collimating element and dispersing the same and a focusing element for receiving light from the dispersive optical element and focusing the same on a detector assembly wherein, where the wavelength dispersion of the dispersed light extends in the x-y direction, the collimating element and the focusing element are formed so as to maintain the desired optical parameters in the x-y plane while having a reduced size in the z direction.
