Antireflective moth-eye structures on curved surfaces fabricated by nanoimprint lithography

In this work, we describe an effective and simple method for surface patterning of 3D objects with antireflective moth-eye structures via UV based nanoimprint lithography using soft stamps. So-called anti-reflective moth-eye structures are subwavelength nanostructures that can reduce the reflection of surfaces over the entire visible spectrum of light. Such broadband antireflective coatings are especially interesting for optical elements like lenses.
