Revolutionizing Aspheric Processing and Low-Cost Prototyping
In the critical stages of product development and validation, the method used to manufacture aspheric optical components often becomes the deciding factor in a project’s success. Traditional mold-based manufacturing can cost tens of thousands to hundreds of thousands of dollars, requiring substantial upfront investment. What's more, if design changes are needed or if the prototype fails validation, all that investment is lost—an outcome with high financial risk. For R&D-driven companies, this represents a major barrier that slows innovation and delays product iterations.
At Yighen Ultra Precision, we’ve redefined the rules of the game with breakthrough technologies that dramatically reduce costs and accelerate development timelines. By leveraging advanced materials and precision machining techniques, we empower businesses to validate their optical designs faster, smarter, and at a fraction of traditional costs.
Yighen Technology manufactures various types of optical lenses, including aspherical, freeform, and Fresnel lenses at low cost.
Innovative Materials and Processes: A New Era of Low-Cost Optical Development
Instead of relying on expensive molds, Yighen Ultra Precision directly machines aspheric lenses from optical-grade resin blocks—bringing prototyping costs down to just a few thousand yuan. This approach opens up a fast and affordable pathway for product testing and iteration, especially during early-stage development.
We have access to an extensive material library, allowing us to select the most suitable optical resin based on each application’s specific requirements:
Our selection includes widely used optical resins such as polycarbonate (PC), known for its excellent impact resistance and mechanical strength, and polymethyl methacrylate (PMMA), prized for its high transparency and environmental durability. These materials are ideal for applications where both optical performance and structural integrity are essential.
For projects demanding higher optical stability, we offer a range of Zeonex materials, including T62R, K26R, 480R, E48R, K52R, and K22R. These resins exhibit low birefringence, minimal moisture absorption, and high glass transition temperatures, making them perfect for precision optical systems where thermal and environmental stability are crucial.
Additionally, we support other high-performance resins such as APL5013, APL5014, EP5000, EP9000, OKP-1, and OKP-4, each offering unique combinations of optical clarity, thermal resistance, and mechanical properties tailored to specialized use cases. For infrared applications, we also provide materials like germanium, zinc selenide, calcium fluoride (fluorite), and infrared composites. While fluorite offers exceptional heat resistance and is capable of freeform shaping, it requires special handling due to its abrasive dust, which can damage standard equipment. Despite its higher processing cost compared to plastics, it remains a preferred choice for high-end optical systems.

With our state-of-the-art ultra-precision single-point diamond turning technology, we shape these materials into high-quality prototypes with sub-micron accuracy. Guided by computer numerical control (CNC) systems, our machines operate like master artisans, carving complex optical surfaces directly from solid blanks. This eliminates the need for costly molds and shortens lead times from weeks or months to just a few days—allowing our clients to test, refine, and launch products faster than ever before.
Advanced Capabilities: Leading the Field in Complex Optics Manufacturing
Beyond cost-effective aspheric prototyping, Yighen Ultra Precision excels in the production of highly complex optical elements. Our technical expertise places us at the forefront of precision optics manufacturing.
One of our key strengths lies in freeform surface machining, often considered the “Mount Everest” of optical engineering. Freeform optics feature irregular, non-symmetrical shapes that demand extreme precision in both toolpath planning and process control. Through proprietary five-axis machining technology and advanced error compensation algorithms, we achieve surface form accuracy at the sub-micron level (PV value) and surface roughness below the nanometer scale (Ra). This capability enables the creation of cutting-edge optical components used in high-end imaging systems, laser optics, and aerospace applications.
We also specialize in the fabrication of non-rotationally symmetric Fresnel lenses, including linear and elliptical variants—structures that pose significant challenges due to their complexity. Using slow tool servo technology combined with nanometer-level motion control, we produce Fresnel lenses with exceptional dimensional accuracy and surface finish. Whether it’s the precise definition of individual facets or the uniformity across the entire lens structure, our products meet and exceed industry standards, filling critical gaps in China’s domestic optical manufacturing landscape.
