Patent number: 11868049Abstract: Described is a telecentric illuminator that can be used, for example, in a mask aligner system for semiconductor wafer processing or as part of a solar simulator system for characterization of solar cells. The telecentric illuminator includes a tapered optic, a lens group having a plurality of lenses and an aperture stop, and a hybrid Fresnel lens. The Fresnel lens is disposed at a position along the optical axis of the telecentric illuminator to generate a telecentric image of the aperture stop at an illumination plane. The Fresnel lens may have a curved central portion and the aperture stop may be apodized to achieve desired illumination characteristics and improve the resolution of a mask aligner system.Type: GrantFiled: April 12, 2022Date of Patent: January 9, 2024Assignee: Innovations in Optics, Inc.Inventors: Thomas J. Brukilacchio, David W. Pierce

Patent number: 8746943Abstract: A light emitting diode (LED) based illumination system with particular application to large scale side lighted liquid crystal displays (LCD). The invention uses on board closed loop intensity control in conjunction with red, green and blue (R,G,B) LED die and a hybrid non-imaging optical system to overcome substantial temperature dependence, loss in intensity with time, increased system cost and complexity, and decreased dynamic range. The invention obtains a large color gamut in excess of 110% of the NTSC (National Television System Committee) recommendation. A high performance thermal management design, the use of “chip on board” technology, compact and efficient collection optics, and on board closed loop intensity control increase and maintain luminous performance and decrease cost relative to less efficient RGB LED approaches. One or more line sources can be generated for applications other than in lighting LCD displays.Type: GrantFiled: October 24, 2008Date of Patent: June 10, 2014Assignee: Innovations In Optics, Inc.Inventor: Thomas J.

Patent number: 8403527Abstract: The invention relates to a light emitting diode (LED) light source comprising an LED die, or a closely packed die array or matrix of die arrays, substantially and efficiently coupled to non-imaging collection optics. The non-imaging collection optics operate to provide a homogenized LED output having a near field whose intensity is highly uniform and a reduced far field extent substantially preserving the étendue (area, solid angle, index squared product) of the LED output. The near field, in turn, is imaged by a downstream relay lens to an illumination plane a specific distance away.Type: GrantFiled: October 17, 2011Date of Patent: March 26, 2013Inventor: Thomas J.
