    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: 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.
