Abstract:
1. An optical mechanism of a miniaturized spectrometer, comprising: an input unit that receives an optical signal and directs the optical signal to an interior of the optical mechanism; a first waveguide plate having a first reflective surface; a second waveguide plate substantially parallel to the first waveguide plate, the second waveguide plate having a second reflective surface opposite the first reflective surface, the first reflective surface and the second reflective surface forming an optical channel for transmitting the optical signal; a miniature diffraction grating that separates the optical signal into a plurality of spectral components received by an image capture module located at an end of the miniaturized spectrometer; and a first light extinction module and a second light extinction module that are arranged on opposite sides of the optical channel, a respective cross-section of each of the first light extinction module and the second light extinction module has a serrated side facing the optical channel and configured to absorb optical signals with incident angles greater than a predefined angle.
