Patent number: 7813054Abstract: Optical elements for efficiently diffusing or shaping light have substrates with saddle shaped structures on their surfaces which provide substantially uniform light along a predefined angular range. Each saddle shaped structure defines an aperture of a lens, where the outer boundary of such aperture, when viewed normal to surface, may be of one of more different shapes, such as square or rectangular, circular, hexagonal, oval, or other geometric or arbitrary shape which may represent a full saddle shape or a subset region thereof. A plurality of saddle shaped structures may be arranged periodically or randomly along the surface. An optical element with a saddle shaped structure is referred to as a saddle lens, and optical elements with different shaped saddle shaped structures provide different types of saddle lenses.Type: GrantFiled: December 14, 2007Date of Patent: October 12, 2010Assignee: RPC Photonics, Inc.Inventor: Tasso R.

Patent number: 7092165Abstract: Microlens arrays (105) having high focusing efficiencies are provided. The high focusing efficiencies are achieved by accurately producing the individual microlenses making up the array at high fill factors. Arrays of positive microlenses are produced by forming a master having a concave surface-relief pattern (101) in a positive photoresist (21) using direct laser writing. Through this approach, the problems associated with the convolution of a finite laser beam with a desired profile for a microlens are overcome. The microlens arrays of the invention have focusing efficiencies of at least 75%.Type: GrantFiled: December 17, 2004Date of Patent: August 15, 2006Assignee: Corning IncorporatedInventors: G.
