ABSTRACT:
A method whereby the thickness distribution of a vapor deposited layer, such as an interference filter deposited on a skirted substrate such as a glass faceplate for a projection television tube, is improved by shielding the substrate from indirect flux of vapor so as to reduce the shadowing effect of the skirt upon the thickness distribution of the deposited layer, thereby improving the white field uniformity of the resultant projection image.
