In order to reduce the effect of wavelength drift on measuring spectrum
a simple device was designed for wavelength calibration of PC2000-PC/104 spectrometer using Ocean Optics' HG-1 Mercury-Argon Lamp. Wavelength calibration coefficients were calculated through regression analysis after several ordinal numbers of CCD's pixels corresponding to Mercury-Argon Lamp's spectral lines were measured. The residuals of certain spectral lines were computed using the coefficients measured and the ones from factory
the degree of fitting for regression equation was estimated using the new coefficients. The final results validated the wavelength calibration model.
