△ Arbitrary control of scatter distribution and profile 

△ Each micro lens element designed and controlled for scatter properties 

△ Divergence angle flexibility from 0.25 degrees up to ~150 degrees

△ Low sensitivity to alignment in 3D use case 3D

△ Feature sizes ~100x to 1000x larger than DOE

△ Robust to Fabrication errors 

△ No underlying repetitive features 

△ No zero order
