1. A spectroscopy system, comprising:
a spectrometer, comprising:
a collimating lens that receives light rays therethrough;
a transmission grating having tilted fringes within a volume of the transmission grating, the transmission grating being optically coupled to the collimating lens, the transmission grating being formed by modulating a refractive index to produce fringe planes that are oriented relative to each other through a depth of a grating material; and
a focus lens that is optically coupled to the transmission grating;
a detector optically coupled to the focus lens, wherein the detector converts optical signals into electrical signals to render spectral data; and
a computing device electrically coupled to the detector, the computing device receiving the spectral data from the detector.
