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:
- Eliminates Spherical Aberration: Directs all incoming light to a single, precise focal point.
- 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).

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.
What is the typical lead time for custom aspheric prototypes?
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.
Can you replace my existing multi-lens assembly with a single asphere?
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.
