The applications of micro-structured surfaces have been more widespread. They have attracted a lot of attention in the research communities, especially in optics and opto-mechatronics. With the functional requirements, much effort has been made to generate micro-structured surface with self-cleaning properties by methods of using either low-surface-energy materials or modifying the surface structures. However, relative little research work has been found on producing micro-structured surfaces with both optical performance and self-cleaning properties. This paper presents a study for modeling and characterization of the generation of micro-structured surfaces with the properties of self-cleaning and optical performance. A series of simulation and experimental studies have been undertaken to obtain the optimum parameters of the structured surfaces. A typical frustum ridge structured surface has been designed and produced by ultra-precision raster milling, and the geometrical form, static water contact angle, and optical performance are characterized. The preliminary results show that the designed and fabricated micro-structured surfaces with a specified geometrical pattern and scales exhibit both self-cleaning function and the expected optical performance.
