Ophthalmic Industry

In the ophthalmology industry, ultra-precise single-crystal diamond tools (SCD) are mainly used for the precise processing of resin lenses and contact lenses. 

Its high hardness and low friction make it an ideal tool for processing non-metallic materials such as resins and optical glass. Especially in the production of resin lenses, the tool can directly achieve mirror-level turning (with a surface roughness of Ra 4μm or less), eliminating the traditional polishing process and significantly improving processing efficiency and consistency of the finished product.

In the manufacturing of contact lenses, SCD tools are mainly used for processing high-precision molds, such as the aspheric mold cores of contact lenses. Through ultrasonic vibration cutting technology, the cutting tool can achieve nanoscale surface quality (waviness <10nm, shape accuracy ±50nm), ensuring that the curvature radius and light transmittance of contact lenses meet medical-grade standards.

With its technical advantages such as high thermal conductivity and chemical stability, ultra-precision single crystal diamond tools have driven the eyewear industry to upgrade towards high-precision and low-loss manufacturing. In the high-end eyewear sector, SCD supports the research and development of customized aspheric lenses and lightweight contact lenses, meeting the strict requirements for optical performance and wearing comfort.
