Abstract
In recent years, micro-optics has become a rapidly developing field in science and technology. Micro-lenses are small, precise optical elements that can be used to focus light, magnify images, or create complex optical effects. They have numerous applications in fields such as microscopy, imaging, and display technologies. However, the development of new methods for creating micro-lens arrays is essential for further progress in this field. The current methods of fabrication, such as photolithography and etching, have limitations in terms of precision, cost, and scalability. Therefore, there is a need for more advanced techniques that can produce high-quality micro-lens arrays with greater efficiency and lower cost. One such technique is the controlled dewetting of a polymer blank on a substrate with low surface energy. By varying the size of the blank, different focal lengths can be achieved, and by adjusting the placement of the blanks, a sophisticated array of microlenses can be created.
