Westerman, Hattori, Daniels & Adrian, LLP
Color dispersion apparatus and spectrometer
The present disclosure relates to a dispersion apparatus. The dispersion apparatus may include an optical substrate; a grating layer on a first side of the optical substrate; and a light outlet layer on a second side of the optical substrate, the second side opposite the first side of the optical substrate. The grating layer is configured to perform dispersion of incident light into first-order diffracted beams having target wavelengths and transmit the first-order diffracted beams into the optical substrate, and wherein a diffraction angle of each of the first-order diffracted beams having the target wavelengths is smaller than a total reflection angle between the optical substrate and air. The light outlet layer is configured to extract the first-order diffracted beams having the target wavelengths in the optical substrate.
