Spectrometer and spectral detection and analysis method using the same

A spectrometer, comprising:

• an optical device configured to receive a polychromatic incident light and emit at least two kinds of monochromatic light, the optical device comprising:
• a first substrate comprising a transparent material and comprising a light incident surface and a light emitting surface parallel to each other, the light incident surface and the light emitting surface being provided with a light blocking layer, the light blocking layer on the light incident surface comprising at least one light incident opening, the light blocking layer on the light emitting surface comprising at least one light emitting opening, the at least one light incident opening being aligned with the at least one light emitting opening;
• at least one light filter, the at least one light filter corresponding to the at least one light emitting opening, wherein each light filter is in a corresponding light emitting opening, wherein each light filter comprises at least two light filtering units, and wherein a light filtering unit of the at least two light filtering units is configured to transmit light having a wavelength within a wavelength range;
• a detection device configured to receive the at least two kinds of monochromatic light emitted from the optical device and generate a detection signal, the detection device comprising:
• a support component comprising a light receiving surface that is adjacent and parallel to the light emitting surface of the first substrate so that a gap is formed between the light receiving surface and the light emitting surface to form a test channel;
• and
• at least one detector in the light receiving surface of the support component, and facing the at least one light filter in a one-to-one relationship, wherein each detector comprises at least two detection units that face at least two light filtering units in a corresponding light filter in a one-to-one relationship, wherein the at least one detector is configured to receive the monochromatic light emitted from the at least two light filtering units and passing through the test channel, and configured to generate electrical signals based on the monochromatic light that was received,
• wherein the monochromatic light emitted from the at least two light filtering units emit light along a direction perpendicular to the light emitting surface.
