Fresnel Lens Machining Services – Linear, Elliptical, Convex

Precision Fresnel Lens Machining

Linear, Elliptical & Convex Structures for Optical and Photonic Systems

At Yighen Ultra Precision, we help engineers turn complex optical ideas into reality—especially when it comes to Fresnel lenses. From linear Fresnel lens machining to elliptical and convex Fresnel fabrication, we offer precision manufacturing solutions that combine design flexibility with nanometer-level surface accuracy.

Whether you're working on solar optics, LED beam shaping, or projection systems, our team delivers high-quality Fresnel lenses ready for integration.

🔹 What Makes Fresnel Lens Machining So Versatile?

Fresnel lenses offer the optical power of curved lenses—without the weight and bulk. By using concentric or linear grooves, they focus or redirect light efficiently across large surfaces. At Yighen, we’ve refined our Fresnel lens processes to support:

• Compact optical architectures

• Lightweight lens designs

• Multi-surface and freeform geometries

• Prototyping + injection replication workflows

“For many of our clients, the challenge isn’t just building a Fresnel lens—it’s getting the exact groove profile that works optically and can scale to production. That’s where we come in.”

📏 Linear Fresnel Lens Machining

Linear Fresnel lenses are often used in solar concentrators, architectural daylighting, and LED panels. Their straight-groove design offers efficient linear light control, ideal for wide-area illumination.

We manufacture linear Fresnel optics using high-precision CNC fly-cutting and diamond tooling systems.

Capabilities:

• Groove depth accuracy within ±0.5 μm

• Profile uniformity across 100–300 mm spans

• Surface roughness down to Ra < 10 nm

• Materials: PMMA, Zeonex, COC, PC

From rapid prototyping to mold insert production, we support both optical-grade sheets and custom concentrator components.

🌀 Elliptical Fresnel Lens Fabrication

Elliptical Fresnel lenses are ideal when asymmetric light control is needed—such as in beam steering, photodetectors, or portable projection systems. These lenses shape light unevenly to concentrate it more precisely where it's needed.

At Yighen, we use multi-axis CNC and custom elliptical groove modeling to deliver high-performance elliptical Fresnel lenses.

Key Features:

• Seamless modeling of elliptical segments

• Tight groove tolerance with PV < 0.2 μm

• Smooth stitching of compound curves

• Sizes down to miniaturized optics for embedded systems

Have a unique beam profile in mind? Our engineers can co-develop the lens with you—starting from simulation, through DFM, to tooling and production.

🔮 Convex Fresnel Lens Manufacturing

Convex Fresnel lenses combine curved surfaces with Fresnel groove structures to create powerful focusing elements—while keeping components light and thin.

These are commonly used in:

• Solar thermal systems

• AR headsets and HUDs

• Wide-angle or panoramic imaging

Our slow-tool servo CNC + error compensation workflows allow us to machine spherical or freeform convex Fresnel surfaces with high repeatability.

Capabilities:

• PV form error control to ±0.1 μm

• Surface finish Ra < 5 nm

• Supported diameters: 10 mm to 200 mm

• Replication-ready tooling for high-volume molding

🔦 Application Scenarios

Have a custom groove pattern or hybrid surface in mind? We support multi-geometry Fresnel lens development and integrated freeform components.

❓ Frequently Asked Questions

Q: Can you produce hybrid Fresnel lenses—like convex + elliptical?
A: Yes. We use 5-axis machining and custom CAM programming to generate multi-mode Fresnel surfaces, including freeform combinations.

Q: What’s the smallest detail you can machine?
A: We routinely achieve groove step accuracy of ±0.5 μm and surface roughness Ra < 5 nm depending on material and design.

Q: Do you offer mold inserts for Fresnel replication?
A: Absolutely. We machine high-durability steel or copper alloy inserts, and apply shrinkage modeling for plastic injection.
