Aspheric Lens Design Services | Precision Optical Engineering

At Yighen Ultra Precision, we specialize in the design of aspheric lenses—optical surfaces that correct aberrations beyond the reach of spherical optics. Aspherics allow higher imaging performance with fewer elements, enabling compact, lightweight, and cost-effective systems.

Our design team develops aspheric prescriptions that balance performance, manufacturability, and tolerance, ensuring they work both in simulation and in production.All of our projects are built on the foundation of our broader Optical System Design framework, which connects requirements, architecture, and verification.

Why Aspheric Lenses?

Spherical optics are limited in how they correct spherical aberration, coma, and distortion. Aspheric lenses overcome these limits, offering:

• Higher image quality — improved MTF and reduced aberrations

• Fewer optical elements — simplifying systems, lowering weight and assembly complexity

• Compact architectures — shorter track lengths, smaller packaging, reduced cost

• Mature manufacturability — widely supported with molding, grinding, and diamond turning

Compared to freeform surfaces, aspherics are simpler, lower-risk, and more cost-effective, making them ideal for many imaging and illumination applications.

What You Receive

• Optimized aspheric prescriptions for your wavelength and detector requirements

• Zemax/CODE V design files including surface definitions, coefficients, and optimization history

• Tolerance report with sensitivity analysis and Monte Carlo validation

• Recommendations for glass or polymer substrates, coatings, and molding/turning options

• Verification plan for interferometry or profilometry suited to aspheric metrology

Our Approach to Aspheric Lens Design

1. Requirement capture — resolution, field of view, spectral range, packaging constraints

2. Architecture selection — refractive vs. reflective, single vs. multi-element aspheric strategy

3. Optimization — aberration correction, distortion control, MTF/EE improvements

4. Tolerance analysis — misalignment sensitivity, assembly robustness, yield prediction

5. Manufacturability check — slope limits, sag profiles, and compatibility with molding or turning

6. Verification plan — methods for validating aspheric surfaces and assembled performance

Applications of Aspheric Lenses

• Imaging lenses — camera objectives, microscope modules, and inspection optics

• Consumer products — compact optics in smartphones, projectors, VR headsets

• Medical devices — endoscopes, ophthalmic instruments, and diagnostic imaging

• Illumination systems — LED collimators, laser beam shaping, projection optics

• Automotive & Defense — night vision optics, HUD projection lenses, lightweight collimators

• The athermalization strategy described here was validated as part of a system-level Optical System Design.

Frequently Asked Questions

Q: What is an aspheric lens?
A: An optical surface that departs from spherical curvature, correcting aberrations and improving performance.

Q: How is aspheric design different from freeform design?
A: Aspherics are rotationally symmetric and simpler to manufacture, while freeforms are non-symmetric and enable more advanced, compact architectures.

Q: What are the benefits of aspheric lenses?
A: They reduce element count, improve MTF, minimize distortion, and allow smaller, lighter optical systems.

Q: Are aspherics easy to manufacture?
A: Yes. Aspheric fabrication is mature, with options including molding, precision grinding, and single-point diamond turning.

Q: Do you provide native aspheric design files?
A: Yes—Zemax/CODE V files with coefficients, tolerance setups, and design documentation.

Q: How does this service relate to overall system design?
A: It is part of our larger Optical System Design service, where all subsystems—custom optics, freeforms, aspherics, and analysis—are integrated into a coherent framework.
