Method for replicating holographic optical elements |
摘要 |
A method for making an optical image element having a high aspect ratio relief hologram comprising the sequential steps of (a) applying a dry photohardenable film to a surface of a transparent dimensionally stable substrate; (b) embossing the exposed surface of the photohardenable film with the holographic image by applying thereto under pressure a stamper containing a reverse relief image of the hologram having an aspect ratio of at least 3:1; (c) passing actinic radiation through the transparent substrate and the photohardenable film to effect hardening of the photohardenable film while it is in contact with the stamper; and (d) separating the stamper die from the embossed photohardened film.
