We show you a novel coating method to easily manufacture similar biomimetic large arrays of antireflective moth-eye nanostructures. Optical elements are an important part of many modern-day technical appliances. A major problem of all these optical elements is the reflection of light. These reflections can cause a loss in image brightness, create double images, and might even inflict damage to the equipment. Moths have solved the problem of unwanted light reflectivity millions of years ago using a dense pattern of nano-sized pillars on their eyes. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart have developed nano.AR, a novel coating method to easily manufacture similar biomimetic large arrays of antireflective moth-eye nanostructures. The project is funded by the BMBF VIP program.
