This work presents a homemade multirole 3D-printed modular spectrometer (MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV–vis absorption, fluorescence emission, flame emission/absorption, glow discharge, even Raman spectra. The is designed cheap, flexible, its inner structure displayable, making it suitable for range applications age groups. assembly process allows clear understanding the basic monochromator, core component spectrometers, well reveals connections similarities between spectral analysis methods. Despite being disassembled, robust, easy calibrate, highly precise, both qualitative quantitative analysis. study provides valuable tool those seeking practical educational approach spectroscopy.
