A portable spectrometer prototype is built to study wavelength calibration for flat-field grating spectrometers. An accurate method called parameter fitting presented. Both optical and structural parameters of the are included in model, which accurately describes relationship between pixel position. Along with higher accuracy, proposed can provide information about errors installation components, will be helpful alignment.
