Ultra Precision CNC Machining for Mirrors and Lenses

In the demanding fields of optics, aerospace, defense, and medical imaging, the performance of an entire system hinges on the perfection of its core components: mirrors and lenses. Achieving the necessary levels of accuracy, surface finish, and complex geometry requires more than standard machining; it demands Ultra Precision CNC Machining. This advanced manufacturing discipline is critical for producing optical elements that meet the rigorous specifications for highperformance applications.

Ultra Precision CNC machining goes beyond conventional tolerances, operating in the submicron realm. For mirrors, especially those used in highpower laser systems or astronomical telescopes, surface finish and form accuracy are paramount. Any imperfection, even at the nanometer level, can lead to scattered light, reduced signal strength, or system failure. Our 5axis CNC milling and diamond turning capabilities allow us to machine substrates like aluminum, copper, and silicon carbide into offaxis parabolas, aspheric surfaces, and freeform optics with exceptional accuracy and minimal subsurface damage.

For lenses, the challenges are equally complex. While initial molding is common for high volumes, the masters and prototypes require the utmost precision. Ultra Precision CNC is indispensable for creating these injection molds and embossing tools with flawless surfaces and exacting profiles. Furthermore, for specialized materials or unique designs not suited to molding, we can directly machine optical elements from crystals like Calcium Fluoride (CaF2) or Zerodur®, achieving the required optical clarity and precise curvature.

The key to success in this niche lies in a synergistic combination of stateoftheart machinery, rigorous process control, and deep material science expertise. Our facility utilizes CNC machines with highresolution feedback systems, temperaturecontrolled environments to mitigate thermal expansion, and advanced metrology equipment such as interferometers and CMMs to verify every dimension and surface characteristic.

We offer a comprehensive "onestop" service, managing the entire process from material selection and CAD/CAM programming to final finishing, coating, and quality assurance. This integrated approach saves our clients valuable time and reduces supply chain complexity, ensuring that their innovative optical designs are realized with reliability and speed.
