Aspheric Lens Machining and Manufacturing Services

Aspheric Lens Machining & Production Services

Precision Surface Fabrication for High-Performance Optical Systems

When off-the-shelf lenses won’t meet your performance goals, custom aspheric optics offer a powerful alternative. At Yighen Ultra Precision, we specialize in the fabrication and production of high-accuracy aspheric surfaces—from single prototype optics to mass-produced lens assemblies—using state-of-the-art SPDT, ultra-precision CNC, and grinding & polishing systems.

Whether you're building a laser module, compact imaging system, or a next-gen AR headset, we help turn your design into reality—with nanometer surface finishes, sub-micron form control, and production-grade consistency.

🔍 What Is Aspheric Machining—And Why Is It So Useful?

Unlike spherical lenses, aspheric optics use surfaces with continuously changing curvature. This helps:

• Reduce aberrations

• Flatten image planes

• Minimize lens count

• Enable smaller, lighter designs

But these benefits come with technical challenges—especially in fabrication.

“We often see clients pushing performance limits with spherical designs, only to realize they need custom aspheres to hit their goals. That’s where our machining systems and process control come in.”

At Yighen, we offer multiple approaches based on material and application:

• SPDT (Single-Point Diamond Turning) for ultra-smooth surfaces in optical plastics and metals

• Ultra-precision CNC for tight form tolerances on large or complex parts

• Glass grinding & polishing for volume glass optics and mold inserts

We regularly deliver form accuracy down to PV ≤ 0.1 μm and surface roughness as low as Ra ≤ 2 nm, validated with full-surface metrology.

⚙️ Our Aspheric Machining Capabilities

Key Equipment:

• Toshiba ULC-100 SPDT Lathes for ultra-precise turning

• Nanotech 250 / 650 CNC Machines

• ULG-100D for precision glass grinding

• UA3P 3D profilometers for non-contact surface inspection

All processes take place in climate-controlled workshops to prevent thermal drift and maintain micron-level dimensional stability.

🛠️ Aspheric Lens Production: From Sample to Scale

We don’t just machine optics—we help you scale them.

Whether you're testing a single prototype or preparing for high-volume rollout, our production workflow adapts to your timeline and budget:

• Prototyping with SPDT or CNC (Ra ≤ 2 nm surfaces)

• Mold insert machining for plastic lens replication

• Shrinkage-compensated tooling design

• Precision injection molding (metal- and nickel-free options)

• Batch QA with interferometry, CMM, and profilometry

We’ve helped clients go from CAD to production in under 6 weeks—without compromising on optical performance.

Our aspheric lens manufacturing services support:

• Glass optics – polished aspheres, flats, and hybrids

• Plastic optics – injection-molded lenses with optical clarity

• Tooling – mold inserts Ø < 8 mm, roughness < 2 nm

🎯 Applications We Serve

Our aspheric optics power a wide range of next-generation systems:

• Medical Devices – surgical optics, endoscope lenses, intraocular implants

• Consumer Optics – smartphone camera modules, VR headsets

• Automotive – AR HUD lenses, ADAS sensors

• Laser Systems – beam shaping, collimators, scanning lenses

• Aerospace & Remote Sensing – lightweight, thermally stable optics for airborne platforms

We routinely collaborate with optical engineers and mechanical teams to optimize tolerances, minimize risk, and accelerate development.

❓ Frequently Asked Questions

Q: What's the difference between spherical and aspheric lenses?
A: Spherical lenses have constant curvature. Aspheric lenses vary continuously, reducing aberrations and allowing compact, high-performance designs.

Q: Can you machine aspheric glass optics?
A: Yes. We offer ultra-precision grinding and polishing for glass substrates, including fused silica and optical glasses, and mold insert production for plastic replication.

Q: What tolerances do you hold?
A: Surface roughness Ra ≤ 2 nm and form accuracy PV ≤ 0.1 μm are standard. We also support λ/10 surface flatness for interferometric systems.

Q: Do you support plastic injection molding?
A: Absolutely. We machine mold inserts in hardened steel or copper alloys, and apply shrinkage compensation for high-precision optical replication.
