AO-2999 APPARATUS AND IMPROVED METHOD OF BONDING A POLARIZING FILM TO AN 6/24/?5 sam OPTICAL SUBSTRATE WITHOUT DISTORTING THE UNIFORM DIRECTION OF POLARIZATION ABSTRACT OF THE DISCLOSURE A stretching frame and vacuum former having an identical geometric shape with the vacuum former being proportionally reduced in peripheral dimensions, permits a stretched molecularly- oriented, light-polarizing, organic film having a uniform direction of polarization to be bonded to a substrate without distorting the direction of polarization. The method is practiced by supporting the molecularly-oriented, light-polarizing, organic film in contact with the edge of the vacuum former with the vacuum former being located substantially equidistant from the stretching frame and then a vacuum is applied to the chamber of the vacuum former to draw the film down onto the optical element. By utilizing a stretching frame and vacuum former having identical geometry, the uniform direction of polarization is not distorted by uneven stretching of the organic film as it is drawn down into contact with the glass element by the reduced pressure. - 1 -
