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: 9891384Abstract: Systems and methods for multiple-pass stripping of an optical fiber are disclosed. The method include irradiating a first portion of the coating with a first beam of radiation having a wavelength at which the coating is substantially transparent and an intensity that exceeds the optical-damage threshold of the coating to form a first damaged coating portion. The method also includes receiving at least a portion of the first radiation beam and redirecting it as a one or more redirected radiation beam to either the first portion of the coating to assist in forming the first damaged coating portion, or to one or more second portions of the coating to form one or more second damaged coating portions. The method additionally includes exposing a section of the central glass portion damaged portions of the coating.Type: GrantFiled: December 5, 2014Date of Patent: February 13, 2018Assignee: Corning Optical Communications LLCInventors: Anthony Sebastian Bauco, Klaus Hartkorn, Daniel Max Staloff

Patent number: 9638862Abstract: Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body having a folded optical axis and at least one alignment feature that supports the end of an optical fiber adjacent an angled planar end wall. The monolithic body also includes a total-internal reflection surface and a lens surface that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot at the image plane.Type: GrantFiled: April 16, 2015Date of Patent: May 2, 2017Assignee: Corning IncorporatedInventors: Venkata Adiseshaiah Bhagavatula, Klaus Hartkorn, Daniel Max Staloff
