Precision Cylindrical Lenses for High-Performance Beam Shaping
At Avantier, we manufacture high-precision cylindrical optics designed for the rigorous demands of laser beam conditioning, spectroscopic imaging, and aerospace metrology. By integrating advanced manufacturing with proprietary CGH (Computer-Generated Hologram) interferometry, we ensure every lens—from standard plano-convex to complex aspheric profiles—delivers the exact wavefront quality your application requires.

Advanced Geometry & Custom Solutions
Our engineering team specializes in complex geometries that go beyond standard catalog offerings.
- Plano-Convex & Plano-Concave: Optimized for line generation and one-dimensional beam expansion.
- Aspheric Cylindrical Lenses: Critical for high-NA laser diode collimation where spherical aberration must be eliminated.
- Specialized Optics: Including achromatic doublets, angled cylindrical mirrors, and off-axis configurations for unique system layouts.
Metrology-Backed Quality Assurance
What sets Avantier apart is our commitment to technical accuracy. We don’t just manufacture; we verify the “as-built” performance against your design nominals.
- Zygo Verifire™ Interferometry: We provide high-resolution surface maps for every component.
- Custom CGH Nulls: Our extensive library of CGH nulls allows for thorough testing of apertures and F/#s that standard setups cannot accommodate.
