| Summary: | Abstract Compound eye biomimetics are extensively studied owing to their high level of functionality. However, optimizing material‐dependent parameters, such as refractive index, is essential for maximizing lens function. Therefore, metal films are deposited on Pantala flavescens compound eyes using a magnetic mirror magnetron cathode, which deposits films at low temperatures without plasma impingement. By increasing the thickness of the film on the compound eye surface, a compound eye mold is successfully fabricated with high heat tolerance. Lens fabrication is achieved using a high‐temperature‐curable resin. The resulting lens comprises numerous uniformly shaped functional units. This method offers a highly reproducible lens‐pouring molding technique using various materials, marking a significant advancement in developing imaging devices and sensors that accurately replicate the functionalities of dragonfly eyes. |
