Custom Optics Engineered for Ion Traps | Neutral Atom Arrays | PIC Platforms | Photonic Quantum Processors

Quantum computing systems demand optical components with nanometer-level tolerances, ultra-low loss, and exceptional thermal and mechanical stability. Avantier designs and manufactures custom optics and fully integrated lens assemblies that meet the extreme precision requirements of ion trap, neutral atom, photonic, and PIC-based quantum architectures.

We partner directly with engineering teams to improve qubit fidelity, optical throughput, and system scalability through precision optics built for real quantum hardware — not just laboratory prototypes.

High-Precision Lens Assemblies for Quantum System Integration

Fully integrated optical assemblies engineered to enhance alignment flexibility, stabilize optical paths, and ensure long-term performance.

Typical assemblies include:

  • Tube lenses for forming the final image
  • Beam shaping lenses for delivering a uniform intensity profile
  • Achromatic lens to maintain focus across multiple wavelengths
  • Relay lenses for transferring an optical image from one plane to another while preserving spatial structure
  • Beam expander to adjust the beam diameter or divergence

Manufacturing advantages:

  • Sub-micron centration tolerances
  • Monolithic or bonded housings
  • Cleanroom and vacuum-rated assembly
  • Interferometric verification
  • Excellent thermal stability

These assemblies reduce engineering overhead by arriving ready to install and alignment-stable.
