Abstract

This work presents a numerical method for determination of spectral transmittance minimum wavelengths of spectrophotometric holmium oxide filter in large band slits. The method used the filter spectral transmittance at 0.05 nm band slit to create a calculated numerical spectral transmittance for 8 and 12 nm band slits. The numerical transmittance minimum wavelength positions for the filter obtained using this method were compared to the results obtained at Mexico National Metrology Institute in the same band slits. The normalized error was the comparison criteria for the results which showed that obtained values were satisfactory according its stated uncertainties.
