Abstract
The present investigation addresses one of the key challenges in the product quality control of transparent polymer substrates, identified in the replication fidelity of sub-μm structures over large area. Additionally the work contributes to the development of new techniques focused on in-line characterization of large nanostructured surfaces. In particular the aim of the present paper is to introduce initial development of a metrology approach to quantify the replication fidelity of produced 500 nm diameter semi-spheres via anodizing of aluminum (Al) and subsequent nickel electroforming to COC injection molded polymer parts. Calibrated AFM measurements were used to develop a model based on scalar diffraction theory able to calculate the expected nickel and COC substrates angular distribution of reflected and transmitted intensity respectively.
