Custom Aspheric Lens Design & Manufacturing: High-Precision Solutions

Avantier is a leading manufacturer of high-precision custom and stock aspheric lenses, engineered to deliver diffraction-limited performance for the world’s most demanding optical systems. From rapid prototyping to high-volume production, we provide the expertise needed to reduce spherical aberration and minimize system weight.

Strategic Applications

Our aspheric optics are integrated into advanced systems across critical industries:

  • Medical & Life Sciences: Endoscopes, high-resolution DNA sequencing, and laser surgery tools.
  • Aerospace & Defense: SWIR/LWIR thermal imaging and satellite reconnaissance.
  • Automotive & LiDAR: Autonomous vehicle sensors and heads-up displays (HUD).

Industrial Metrology: 3D scanning and semiconductor inspection.

Why Choose Aspheric Lenses?

Traditional spherical lenses often suffer from marginal ray deviation, leading to blurred images. Aspheric lenses feature a complex, non-spherical surface profile that:

  1. Eliminates Spherical Aberration: Directs all incoming light to a single, precise focal point.
  2. Reduces Part Count: A single asphere can often replace multiple spherical elements, resulting in lighter, more compact assemblies.

Enhances Edge Clarity: Provides superior image quality across the entire field of view, even at high numerical apertures (NA).

Custom Engineering & Prototyping

We don’t just manufacture; we partner with your engineering team. Avantier provides comprehensive support from Zemax design optimization to final assembly.

Material Selection & Processes

We work with a vast catalog of substrates to suit your specific wavelength requirements:

  • Precision Glass Molding: Ideal for high-volume, cost-effective production of low-temperature glass.
  • CNC Grinding & Polishing: Best for medium volume and large diameter (up to 200mm) glass aspheres.
  • Diamond Turning (SPDT): Specialized for Infrared materials (Ge, Si, ZnSe) and plastics.
  • Magneto-Rheological Finishing (MRF): Used for achieving extreme surface accuracy and figure correction.

Stock Aspheric Lenses: Ready for Immediate Integration

For rapid prototyping and R&D, Avantier maintains a deep inventory of stock aspheres.

  • Laser-Grade Aspheres: Optimized for high-power beam shaping and focusing.
  • Infrared (IR) Aspheres: Germanium and Silicon substrates for thermal sensing.

Uncoated & Coated Options: Available with AR, V-Coat, or Broadband coatings.

Stock Aspheric Lenses 

Avantier maintains a comprehensive inventory of stock aspheric lenses for rapid delivery. These lenses cover a broad range of focal lengths, diameters, and materials, including laser-grade and uncoated optics.

Real-World Applications & Case Studies

Our engineering team doesn’t just manufacture lenses; we solve complex optical challenges. Explore our recent work in high-precision aspheric integration:

  • Infrared Lens Design for Scientific Research: Optimized for Design for Manufacturing (DFM), we developed high-performance IR aspheres that maintain thermal stability and precision in sensitive laboratory environments.
  • Cold Atom Trapping & Imaging: We designed a custom objective lens system capable of trapping and imaging single atoms, requiring extreme numerical aperture (NA) and diffraction-limited performance.
  • Reverse Engineering of Complex Objectives: Leveraging our metrology suite, we successfully reverse-engineered and improved upon existing objective and projection lens designs to enhance throughput and reduce aberrations.

Technical Resource: Performance Comparison

When designing a system, choosing the right lens geometry is critical for MTF (Modulation Transfer Function) performance.

Frequently Asked Questions

How does Avantier verify the surface accuracy of custom aspheres?

Q: How does Avantier verify the surface accuracy of custom aspheres?


A: We use advanced metrology, including non-contact 3D profilometry and laser interferometry. This ensures that the sag profile matches your design coefficients (Qbfs, Qcon) with nanometer precision.

Q: How have advances in manufacturing made aspheric lenses more versatile and cost-effective?


A: Depending on material availability and complexity, typical lead times for custom prototypes range from 3 to 6 weeks. We also offer expedited “Fast-Track” services for urgent projects.

Q: Can you replace my existing multi-lens assembly with a single asphere?


A: In many cases, yes. Our optical engineers can perform a “Lens Count Reduction” analysis to simplify your design, reduce weight, and lower assembly costs without sacrificing optical performance.
