🔷 Fresnel Lenses

Compact Power, Precision Performance – Custom Fresnel Lens Manufacturing

Fresnel lenses condense the functionality of conventional curved optics into an ultra-thin profile. By segmenting the lens surface into concentric rings, Fresnel designs offer lightweight, low-volume alternatives to thick plano-convex or aspheric lenses—ideal for optical systems that demand compactness without sacrificing performance.

At Yighen Ultra Precision, we specialize in the design, prototyping, and volume production of Fresnel lenses in plastic and glass, offering both standard and custom geometries for illumination, imaging, sensing, and projection applications.

🔹 Why Choose Fresnel Optics?

Fresnel lenses are engineered to reduce material thickness and weight while maintaining optical power. Compared to conventional lenses, they offer:

Ultra-thin form factors
Lower material costs
Large-area light collection or focusing
Flexible customization: linear, elliptical, convex, freeform

🔹 Types of Fresnel Lenses We Offer

Fresnel Lens Type	Description
Linear Fresnel Lens	Straight-line grooves for solar, light guides, and LED
Elliptical Fresnel	Optimized for beam shaping and collimation
Convex Fresnel Lens	Thin substitutes for bulky plano-convex lenses
Freeform Fresnel	Custom geometries for AR/VR, automotive optics, etc.
Diffractive Fresnel	Precision control of phase and focus for wavefront shaping

All designs are simulated in Zemax, LightTools, or Code V, ensuring system-level performance optimization before manufacturing.

🔹 Materials & Manufacturing Options

We machine and mold Fresnel lenses using a range of optical-grade plastics and glass, including:

PMMA (Acrylic) – Most common material for molded Fresnel lenses
PC / COP / APEL / ZEONEX / TOPAS – High-precision injection molding and diamond turning
Glass – For higher thermal resistance and environmental durability
Infrared Materials – For IR beam shaping applications (e.g., ZnS, CaF₂)

💡 Prototypes can be diamond turned from PMMA, COP, or APEL blocks before scaling to mold tooling and volume production.
