Abstract: A spectrometer capable of eliminating side-tail effects includes a body and an input section, a diffraction grating, an image sensor unit and a wave-guiding device, which are mounted in the body. The input section receives a first optical signal and outputs a second optical signal travelling along a first light path. The diffraction grating receives the second optical signal and separates the second optical signal into a plurality of spectrum components, including a specific spectrum component travelling along a second light path. The image sensor unit receives the specific spectrum component. The wave-guiding device includes first and second reflective surfaces opposite to each other and limits the first light path and the second light path between them to guide the second optical signal and the specific spectrum component. The first and second reflective surfaces are separated from a light receiving surface of the image sensor unit by a predetermined gap.

Abstract: The invention provides a test strip comprising an identification region coded a screen function of the test strip by a chromaticity coordinates model; a calibration region having a particular color for calibrating an external spectrum analyzer; and a reaction region chemically reacted with a specific specimen for changing its own color. By using the external spectrum analyzer to conduct light splitting of the reflective lights from the recognition and reaction regions of the test strip, automatic recognition and simplified usage can be achieved.

Abstract: An optical mechanism for a miniaturized spectrometer comprises an input unit, an upper waveguide plate, a lower waveguide plate, and a miniature diffraction grating. The input unit is used to receive an optical signal and direct the optical signal to the interior of the optical mechanism. The upper waveguide plate has a first reflective surface. The lower waveguide plate having a second reflective surface aligned substantially parallel to the upper waveguide plate. The first reflective surface is located opposite to the second reflective surface. An optical channel is formed between the first reflective surface and the second reflective surface, so that optical signal from the input unit can travel in the optical channel. The miniature diffraction grating separates the optical signal transmitted in the optical channel into a plurality of spectral components and directs the spectral components to an image capture module at an end of the miniaturized spectrometer.
