Application of nanoimprinting technique for fabrication of trifocal diffractive lens with sine-like radial profile [PDF]

, 2015
The fabrication of submicron-height sine-like relief of a trifocal diffractive zone plate using a nanoimprinting technique is studied. The zone plate is intended for use in combined trifocal diffractive-refractive lenses and provides the possibility to ...
