To meet the demand for portability and low cost to facilitate the widespread application of spectrometers, this paper presents the comparative analysis of different spectrometer types. Taking the crossed Czerny-Turner (C-T) optical path as a reference, we designed and implemented a portable fiber-optic spectrometer based on a crossed C-T structure. An orthogonal crossed dual spherical mirror configuration was adopted to compress the optical path dimensions, and a prototype system was constructed for experimental validation. Through optimized component selection, a low-cost spectrometer with high portability and strong functionality was developed. The prototype system underwent wavelength calibration, and its aberrations were briefly analyzed. Ultimately, the system achieves a spectral resolution of 1 nm within the 381～716 nm wavelength range. This design resolves the traditional trade-off between size and performance in fiber-optic spectrometers, demonstrating significant application value for rapid detection and real-time spectral analysis.
