PowerPhotonic’s axicon array homogenizing beamshapers use a unique freeform direct-write process to fabricate customized axicon array surfaces in fused silica.
These axicon array homogenizers are carefully designed to produce ring shaped spots at the focus of a lens; simultaneously maximizing performance and efficiency. The axicons are laid out in a hexagonal formation in order to maximize the uniformity of the intensity distribution around the ring.
Axicon array homogenizers are highly insensitive to input intensity distribution and positioning within the beam, unlike traditional axicon elements. PowerPhotonic’s fabrication technology also offers the ability to change the thickness of the ring, as well as the extinction ratio in the ring center, by precisely altering the characteristics of the axicons within the array.
