Filed:

Mar 14, 2013

Appl. No.:

13/827234

Inventors:

Klaus Hartkorn - Painted Post NY, US
Daniel Max Staloff - Rochester NY, US

International Classification:

G02B 6/32

US Classification:

385 33

Abstract:

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.

Abstract:

An apparatus comprises an array of light emitting diodes (LEDs), each LED in the array having an asymmetric optical characteristic. The asymmetric optical characteristic of a first subset of LEDs in the array is oriented at an angle of 90, 180, or 270 with respect to the asymmetrical optical characteristic of a second subset of LEDs in the array. The apparatus may be the array of LEDs or an illumination system comprising a light source comprising the array of LEDs. Methods of manufacturing the apparatus are also provided.

International Classification:

G03F 7/20

Abstract:

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.

Abstract:

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.
