🏢 About Yighen Ultra Precision

Yighen Ultra Precision is a high-end optical design and manufacturing company specializing in ultra-precision machining, freeform optics, aspheric lenses, and system-level optical integration. Headquartered in HongKong, China and supported by a global R&D network, we serve clients across the photonics, medical, semiconductor, aerospace, and AR/VR industries.

Our mission is simple: to transform complex optical ideas into functional, manufacturable, and scalable solutions—no matter how ambitious.

🔹 Our Optical Design Philosophy

At Yighen, we are redefining the future of optical design through innovation, precision, and deep technical insight. As a forward-thinking optical design company, we combine advanced theoretical frameworks, patented technologies, and a world-class engineering team to deliver cutting-edge solutions across medical, industrial, and augmented reality (AR) applications.

We don’t just simulate light—we shape how it performs in the real world.

🔹 A Team Built on Expertise

At the core of Yighen’s success lies a team of highly qualified professionals, many of whom hold PhDs and advanced degrees from top-tier global institutions such as Nanyang Technological University (Singapore), the University of Strasbourg (France), and Zhejiang University (China).

With backgrounds in optical engineering, ultra-precision machining, and materials science, our engineers blend academic rigor with hands-on industrial know-how. From correcting chromatic aberrations in AR optics to achieving sub-micron precision in micro-optics for medical imaging, the team consistently pushes the boundaries of what’s optically possible.

🔹 From Theory to Reality

Yighen is more than a design house—we are a technology partner that transforms novel concepts into tangible, manufacturable products.

We have successfully developed and applied advanced theories such as Symmetry Theory and Columnar Waveguide Optics, and translated them into commercial products used in:

• High-resolution endoscopy systems

• Automated optical inspection (AOI) equipment

• Semiconductor metrology platforms

• Aerospace-grade compact imaging modules

We thrive on complexity, and we excel in bringing theoretical innovation into real-world production pipelines.

🔹 Intellectual Property & Innovation

Innovation drives us—and we ensure our clients benefit from it. All custom technologies developed through collaboration are transferred to the client, including:

• Patented ultrasonic-assisted diamond turning

• Proprietary dynamic error compensation algorithms

• Injection molding shrinkage prediction software

Our growing portfolio includes 30+ patents, covering core technologies in optics, AR display, and ultra-precision fabrication.

🔹 Industry Recognition & Growth

Yighen has been recognized for its innovation by both industry leaders and the capital market. We were awarded the Bronze Prize at the Guangdong-Hong Kong-Macao Postdoctoral Innovation Competition, and our patented optical mold core technologies have significantly improved production efficiency and precision across multiple sectors.

Backed by strategic investors, we continue to expand our footprint, grow our nano-machining capabilities, and serve forward-looking clients worldwide.
