CNC Machining for Custom Optical Lenses

In the demanding world of optics, precision is not just a goal—it's a prerequisite. For applications ranging from medical endoscopes and laser collimators to specialized research instrumentation, custom optical lenses are critical components. While traditional grinding and polishing methods have their place, CNC machining has emerged as a transformative technology for producing highprecision, custom optical components with unparalleled flexibility and speed.

Unlike standard spherical lenses, custom optics often feature complex geometries such as aspheric, freeform, or diffractive surfaces. These designs are engineered to correct for specific aberrations and enhance optical performance, but they are incredibly challenging to produce with conventional techniques. This is where 5axis CNC machining excels. Advanced CNC mills, equipped with ultraprecise spindles and diamondcutting tools, can directly machine these intricate shapes from a solid blank of material with submicron accuracy. This process, known as singlepoint diamond turning (SPDT) when applied to plastics and nonferrous metals, creates opticalquality surfaces directly from the machine, often eliminating the need for secondary postpolishing.

The material versatility of CNC machining is a significant advantage for optical applications. Our一站式加工 services encompass a wide range of optical substrates, including:
Optical Plastics: Such as PMMA and Polycarbonate, ideal for lightweight, costeffective lenses.
Metals: Like aluminum and copper, frequently used for laser system mirrors and reflectors.
Infrared Materials: Including germanium and zinc selenide, crucial for thermal imaging systems.
