Precision Glass Lens Array Manufacturing: When Thousands of Lenses Work as One

A Symphony of Light: The Concept Behind Lens Arrays

Imagine an optical system not built around one powerful lens, but thousands—each one microscopic, yet precisely aligned to control light in ways that a single lens never could. That’s the essence of a glass lens array. Rather than focusing all light through a central point, these arrays divide and direct it across multiple paths, enabling new capabilities like parallel imaging, uniform illumination, and enhanced depth perception.

From smartphone cameras that simulate depth-of-field effects to industrial sensors that map surfaces in 3D, lens arrays are quietly transforming how we capture and manipulate light. But their power lies not just in numbers—it’s in precision. Each tiny lens must be identical in shape, orientation, and optical performance, or the entire system can fall out of sync.

At Yighen Ultra Precision, we approach glass lens array manufacturing not as mass production, but as micro-engineering at scale—where every lens is a masterpiece of symmetry and accuracy.

Why Glass? Because Clarity Can’t Be Compromised

While some lens arrays are made from plastic or polymer materials, glass remains the gold standard for high-performance optical systems. It offers superior surface quality, thermal stability, and resistance to wear—making it ideal for environments where long-term reliability and optical clarity are non-negotiable.

We use ultra-pure optical glasses such as fused silica, borosilicate, and ultra-thin float glass to fabricate our glass lens arrays, ensuring minimal internal distortion and maximum transmission efficiency. These substrates also provide a stable base for applying anti-reflection coatings, protective layers, or even hybrid structures that combine refractive and diffractive elements.

Each material choice is guided by the intended application, whether it's for consumer electronics, aerospace imaging, or photonic integrated circuits. At Yighen Ultra Precision, we believe that when you're building an array of thousands, each lens must start with the purest foundation possible.

Engineering Tiny Giants: The Challenge of Mass Micro-Optics

Producing a glass lens array isn't simply about shrinking lenses—it's about maintaining perfection across hundreds or even thousands of individual optical units. Traditional machining methods often struggle with this kind of repetitive precision, requiring specialized tooling, advanced molding techniques, and ultra-fine polishing processes.

Our process begins with master mold creation using ultra-precise diamond turning, followed by replication through hot embossing or UV imprinting on high-quality glass substrates. This allows us to create microlens arrays with radii measured in microns while maintaining sub-nanometer surface finishes.

Once formed, each lens undergoes rigorous inspection using interferometry, profilometry, and wavefront analysis to ensure optical consistency across the entire array. Alignment between adjacent lenses is verified down to the micron level, ensuring seamless integration into complex optical systems.

This level of detail is essential—because in a glass lens array, the whole is only as strong as its weakest part.
