Abstract

A coated optical element has at least six contact points not all in a same plane. Each contact point is an optical point of contact. Adjacent contact points subtend an angle between about 25 to about 35 degrees at a center of the coated optical element.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A coated optical element having at least six contact points not all in a same plane, each contact point being an optical point of contact, wherein adjacent contact points subtend an angle between about 25 to about 35 degrees at a center of the coated optical element. 
     
     
         2 . The coated optical element of  claim 1 , wherein the coated optical element has at least twelve contact points. 
     
     
         3 . The coated optical element of  claim 1 , wherein adjacent contact points subtend an angle of about 30 degrees at the center of the coated optical element. 
     
     
         4 . The coated optical element of  claim 3 , wherein for each contact point, the contact point and a closest adjacent contact point subtend an angle of about 30 degrees at the center of the coated optical element. 
     
     
         5 . A three-dimensional array of optical elements, each optical element being a coated optical element according to  claim 1 .
