Diffusers and Beam Homogenizers
 Diffusers are primarily designed for input from a collimated source. At the element, light is diffracted into a defined angular distribution to create a specified output pattern in the far field. Available in a variety of configurations such as circular, top-hat, annular, dipole, quadrapole and custom patterns.
Laser beam homogenizers are essential in medical or machining applications where a spatially consistent beam delivery is required. This can compensate for varied intensity profiles from source to source as well as reduce the effects of coherence.
