Abstract
The invention relates to a multi-resolution optical spectrometer that employs two output lenses of different focal length to provide a broad wavelength range, coarse resolution spectral measurement and a high resolution, lower range spectral measurement. Light dispersed by a virtual image phase array followed by a diffraction grating in two different dispersion orders may be separately focused by the two lenses upon to 2D detector array to provide the two measurements.
