CORRECTING THE MOTION OF A MONOCHROMATOR

摘要

A novel means of correcting the motion (17) of an analytical instrument (10) having a diffraction grating (16) is introduced herein based on the determination of the optimal theoretical parameters in the equation of grating angle versus a selected wavelength. Such a desirable correction method of the present invention not only reduces the amount of wavelength error at the calibration points but also in a novel fashion beneficially corrects for errors in a time - efficient manner between the calibration points to a greater degree than conventional calibration methods.
