Rectangular Lenslet Arrays
Lenslet arrays are used in a variety of applications that include beam homogenization. This knowledge base article demonstrates the setup of an imaging lenslet array for creating uniform incoherent illumination on a detector. The input beam has a gaussian profile with half width equal to the lenslet array size and it is shown that this power profile is homogenized by the lenslet array.
The example file and discussion follow from the technical note on the subject provided by Suss Micro-optics, which can be found here. The reader is encouraged to review their documentation and catalog for further information.
