| Abstract (English): | A diffraction spectrometer was developed, based on low cost commercial elements. The spectrometer was designed with the configuration of a transmission diffraction grating spectrometer with adjustable entrance slit. It was built with com-mercial elements like a holographic grating, collimator lens and a digital projector lens. For detection, a webcam CMOS sensor was used. A MATLAB based program was developed for the equipment, allowing the acquisition and processing of spectra. The optical defects were corrected using a non linear wavelength calibration. The SNR of final spectrum was increased in 14 times by processing the data. The Spectrometer showed an effective resolution of 1.4 nm and a precision of ±0.28nm in final tests, showing to work properly with a cost 10 times lower (in materials) to the commercial price of a similar equipment (Ocean Optics USB4000).

| Abstract (Spanish): | Se desarrolló un espectrómetro de difracción con elementos comerciales de bajo costo. Se diseñó con la configuración de un espectrómetro con rejilla de difracción por transmisión y entrada de luz regulable. Se construyó con elementos comerciales y de descarte como una rejilla de difracción holográfica, lente colimadora y objetivo de proyector digital. Para la detección se usó el sensor CMOS de una cámara web comercial. Se desarrolló un programa de control en MATLAB para la obtención y procesamiento de los espectros con el equipo. Calibrando la longitud de onda de forma no lineal se corrigieron los defectos ópticos. Se incrementó en 14 veces el SNR del espectro final procesando los datos. El equipo presentó una resolución efectiva de 1.4 nm y una precisión de ±0.28 nm en las pruebas finales, demostrando ser funcional con un costo 10 veces menor (en materiales) al precio comercial de un equipo similar (Ocean Optics USB4000).
