Correction of wavelength errors in a digitally recording spectrophotometer.
A simple circuit is described that enables known wavelength errors of a digitally recording spectrophotometer to be corrected. The circuit delays the signal that triggers the recording system. The length of the delay is varied as a function of wavelength to correct for the errors. Significant improvement can be obtained in the measurement of CIE tristimulus values.
