In the demanding fields of aerospace, medical devices, and hightech electronics, the need for custom lenses and optical components is paramount. These are not standard, offtheshelf items but highly specialized parts that demand absolute precision. For such critical applications, CNC (Computer Numerical Control) machining has emerged as a superior manufacturing solution, offering unparalleled flexibility and accuracy for both prototypes and production runs.
Unlike traditional grinding and polishing methods suited for highvolume spherical lenses, CNC machining excels at creating complex, freeform, and asymmetric optical geometries. This capability is essential for modern applications like laser beam shaping, advanced illumination systems, and specialized sensor housings. The process involves a computercontrolled machine tool that precisely removes material from a substrate—such as acrylic (PMMA), polycarbonate, or even optical glasses and crystals—to create the desired optical surface with micronlevel tolerances.
The primary advantage of CNC machining for optics is its rapid turnaround for custom designs. There is no need for expensive and timeconsuming mold fabrication, making it ideal for low to medium volumes and R&D phases. Our expertise in CNC machining allows for the integration of optical surfaces with mechanical mounting features in a single, monolithic part. This eliminates alignment issues and reduces assembly time, enhancing the overall performance and reliability of the optical assembly. Furthermore, we can achieve exceptionally smooth surface finishes, often eliminating the need for secondary polishing or significantly reducing postprocessing time.
