The invention solves the problem of creating wide, optical beams that have uniform intensity through their cross-section.
The invention is a device that creates uniform illumination profiles using a single waveguide structure. Input light can be from another waveguide (e.g., an optical fiber) or a free-space light source.
This invention is useful in optical measurement systems, including optofluidic applications such as cytometry and imaging.
The invention is easy and inexpensive to manufacture and adapt to other systems, is robust (durable), and is small in size and does not require additional optical components.
