Precision-Engineered Large Diameter Optics for Advanced Imaging and Photonics
Avantier specializes in large optics—optical components with diameters exceeding 100mm—engineered for high-precision performance in even the most demanding environments. Our solutions are designed to elevate applications in astronomy, aerospace, satellite communication, laser systems, and scientific imaging.
What Are Large Optics?
Large optics refer to optical elements like lenses, mirrors, prisms, domes, and windows that surpass 100 mm in diameter. These components:- Enable high-resolution imaging with minimal aberration
- Support wide apertures for superior light-gathering capability
- Maintain performance across extreme temperatures, vibrations, and environments
