Photolithography of variable depth gratings on a polymer substrate for the mastering of 3D diffractive optical elements

Abstract : A set of photoresist processes permits the printing of a variable depth sinusoidal profile grating in a positive photoresist layer deposited on a PMMA substrate without degradation of the substrate surface for further moulding tool fabrication with damageless dissolution of the polymer master.
