Abstract
A method and device for smoothly rotating a diffraction grating in a spectrophotometer by means of a galvanometer includes modifications in the software in the microprocessor which controls the galvanometer. The software modifications cause the galvanometer to rotate the grating in a series of discrete steps that stimulate a smooth minimum jerk rotation. The amount of rotation in each discrete step is calculated by the microprocessor.
