Precision Aspheric Lenses: Custom Optical Design
Featured Product from Avantier Inc.
Custom Aspheric Lenses
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.
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.
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.
