Introduction Optical lens cutting requires exceptional precision, especially as lens technology advances in fields like imaging, communications, and medical devices. A frequent challenge in this process is chipping — small fractures or flaking at the edges or surfaces of lenses. Chipping not only reduces product yield but also compromises the optical performance of the final component. This article explores effective methods to minimize chipping during optical lens cutting, with a focus on the benefits of using diamond wire saws over traditional methods. Precision Challenges in Optical Lens Cutting Optical lenses are typically made from brittle materials such as glass, quartz, or certain crystals. During cutting, mechanical stress, tool vibration, or improper cooling can induce microcracks or chips along the cut edges. These imperfections are especially problematic in high-precision applications like camera lenses or fiber optic connectors, where surface quality and structural integrity are critical.
