Laser Beam Shaping Overview - Edmund Optics

A laser beam integrator, or homogenizer, is composed of multiple Ienslets that divide the beam into an array of smaller beams, or beamlets, followed by a lens or other focusing element that superimposes the beamlets at the target plane. They can be used with both coherent laser light and other incoherent light sources.
