Abstract

A method for producing a lens mold suitable for manufacturing a field of micro-lenses is disclosed. The method includes the step of molding the lens mold from a sheaf of closely-packed balls held by a hexagonal mounting.

Claims

exact text as granted — not AI-modified
1 . A method for producing a lens mold suitable for manufacturing a field of micro-lenses, comprising the step of molding the lens mold from a sheaf of closely-packed balls held by a hexagonal mounting.  
   
   
       2 . The method of  claim 1 , wherein the lens mold is cast from silicone.  
   
   
       3 . The method of  claim 1 , wherein the mounting is surrounded by a silicone frame comprising an opening, said opening being aligned with the mounting.  
   
   
       4 . The method of  claim 3 , wherein the silicone frame is produced by filling silicone into the interior defined by a holder frame mounted on a first mold plate and surrounding an arbor of the first mold plate.  
   
   
       5 . The method of  claim 1 , wherein the balls have a radius that is essentially equivalent to the radius of the micro-lenses to be produced.
