Paper Abstract

The holmium oxide solution is a common standard reference material used in the calibration of wavelength scales of spectrophotometers. The wavelength values of minimum transmittance of several bands are reported by national laboratories, these values depend on the bandwidth of the instrument (FWHM) with which the transmittance is measured. In high accurate spectrophotometry the FWHM is smaller than 3nm. In this work we simulate the holmium oxide spectral transmittance and obtain extrapolated values to be used as reference values in the calibration of spectrophotometers with 10nm and 20nm of FWHM.
