Abstract: A spectrograph including light beam reformatting element(s), beam expander(s), dispersive element(s) and light receiving element(s). The light beam reformatting element(s) reformat a received light beam into a reformatted light beam having a first dimension along a first axis that is larger than a dimension of the received light beam along the first axis and a second dimension along a second axis substantially orthogonal to the first axis that is smaller than a dimension of the received light beam along the second axis. The beam expander(s) anamorphically expand the reformatted light beam along the second axis into an expanded light beam. The dispersive element(s) disperse the expanded light beam along the second axis, resulting in a dispersed light beam. The light receiving element(s) receive the dispersed light beam. The light receiving element(s) may include one or more detectors to measure spectral intensity of the dispersed light beam.

Abstract: An optical slicer for generating an output spot comprising an image compressor which receives a substantially collimated input beam and compresses the beam, wherein the input beam, if passed through a focusing lens, produces an input spot; an image reformatter which receives the compressed beam to reformat the beam into a plurality of sliced portions of the compressed beam and vertically stacks the portions substantially parallel to each other; and an image expander which expands the reformatted beam to produce a collimated output beam which, if passed through the focusing lens, produces the output spot that is expanded in a first dimension and compressed in a second dimension relative to the input spot.
