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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Color dispersion apparatus and spectrometer","description":"The present disclosure relates to a dispersion apparatus.
