Abstract
An optical printing positioning system is set forth. The system includes a cavity for retaining an optical surface having an inner surface dimensioned and configured to maintain and to constrain an optical surface disposed therein when the optical surface undergoes a printing process.
Claims4
An apparatus comprising:
- a plate including a bottom, sides, and an inner area being a cavity, wherein the cavity having an array of arcuate curved walls which do not extend beyond a top surface of the sides, the sides further comprise an inner wall surface being arcuate with a portion of an inner wall surface extending inwardly and configured to selectively receive more than one optical workpieces with the inner wall surface having an inner top surface curve to maintain and to constrain the optical workpieces selectively disposed therein when undergoing a printing process over at least a portion of the optical workpieces;
- and an aperture in the side forming an opening through the bottom of at least one of the array of arcuate walls to facilitate removal therefrom of the optical workpieces.
An apparatus comprising:
- a plate including a bottom, sides, and an inner area being a cavity, wherein the cavity having an array of rectilinear walls that conform to a desired lens or prism array which do not extend beyond a top surface of the sides, the sides further comprise an inner wall being arcuate with the top surface extending inward configured to selectively receive one or more optical workpieces, the top of the sides formed and shaped to maintain and constrain the optical workpieces selectively disposed therein when undergoing a printing process over at least a portion of the optical workpieces;
- and an aperture in the side forming an opening through the bottom of at least one array of rectilinear walls to facilitate removal therefrom of the optical workpiece.
An apparatus comprising:
- a plate including a bottom, sides, and an inner area being a cavity, wherein the cavity having an array of tetrahedron-prism walls which do not extend beyond a top surface of the sides, the sides further comprise an inner wall being arcuate with the top surface curving inward configured to selectively receive one or more optical workpieces with the inner wall having the inner top surface maintain and constrain the optical workpieces selectively disposed therein when undergoing a printing process over at least a portion of the optical workpieces;
- and an aperture in the side forming an opening through the bottom of at least one array of tetrahedron-prism walls to facilitate removal therefrom of the optical workpiece.
