An optical beam homogenizer divides and redirects an incident beam to provide uniform irradiation to a plane surface. The beam homogenizer is particularly useful in an apparatus and method for uniform laser irradiation of materials. The apparatus comprises a laser, a beam homogenizer, and a support ...

Santa Barbara Research Center, W C Schubert, W K Denson Low, January 7, 1997: US05591975 (52 worldwide citation)

A light source radiates an infrared beam that passes through a chopper, a calibration cell and the exhaust plume of a motor vehicle passing in front of the source. A photosensor assembly includes a plurality of photodetectors which are spaced closely adjacent to each other and simultaneously sense t ...

An optical beam homogenizer includes an entrance pupil through which a non-uniform optical beam propagates. A first optical component having plural flat surfaces receives the input beam. The flat surfaces of the first optical component effectively segment the entrance pupil by dividing the input bea ...

Fortin Michael A, Dang Theodore H: Improved optical beam integration system. Xmr, HETHERINGTON Michael, January 5, 1995: WO/1995/000865

An optical beam homogenizer has been improved to emphasize a dual axis, high aspect ratio spot sizing capability. The optical system alters the aspect ratio of the beam by moving three of the four lenticular arrays (12, 14, 16, 18) within the homogenizer. The integrity of dimensional control is main ...
