Abstract
The thickness distribution of a vapor deposited layer such as an interference filter having deposited on a moving substrate such as a glass faceplate for a projection television tube, is controlled along an axis in the direction of travel of the substrate by employing at least one rotatable dodger to partially shield the substrate as it passes behind the dodger during deposition.
