Publication number: 20200004013Abstract: Light homogenizing elements are described. The light homogenizing elements include lens arrays with corrective features designed to improve the uniformity of light fields produced by optical sources. The corrective features include masks placed at selected positions of selected lenslets in a lens array. The corrective features block or reduce the transmission of light through the lens array at the selected position to correct for spatial or angular non-uniformities in a light field produced by an optical source. Illumination systems that include a corrected lens array coupled to a light source produce highly uniform light fields. Applications include microlithography.Type: ApplicationFiled: June 6, 2019Publication date: January 2, 2020Inventors: Joshua Monroe Cobb, Paul Francis Michaloski, Daniel Max Staloff

Patent number: 10488176Abstract: A metrology apparatus has an illumination source that directs collimated light to a reference surface and to an optical component having a test surface that is in parallel with the reference surface. A first imaging lens defines a Fourier transform plane for light reflected from the reference surface and the test surface. A spatial filtering element is actuable to a blocking position that blocks specular light at the transform plane. A second imaging lens forms, at an image plane, an image of the test surface. A sensor array generates image data from received light at the image plane.Type: GrantFiled: June 15, 2017Date of Patent: November 26, 2019Assignee: Corning IncorporatedInventors: Thomas James Dunn, Paul Francis Michaloski

Publication number: 20190324592Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.Type: ApplicationFiled: March 11, 2019Publication date: October 24, 2019Inventors: Minghan Chen, Jacques Gollier, Ming-Jun Li, Paul Francis Michaloski, William James Miller, Daniel Aloysius Nolan

Patent number: 8922750Abstract: In a lithographic projection system, a corrective optic in the form of one or more deformable plates is mounted within telecentric image or object space for making one-dimensional or two-dimensional adjustments to magnification. The deformable plate, which can be initially bent under the influence of a preload, contributes weak magnification power that influences the magnification of the projection system by changing the effective focal length in object or image space. An actuator adjusts the amount of curvature through which the deformable plate is bent for regulating the amount of magnification imparted by the deformable plate.Type: GrantFiled: October 20, 2010Date of Patent: December 30, 2014Assignee: Corning IncorporatedInventors: Robert D.
