Our photonic raw materials (fused silica, rods, preforms) are foundational to many high-tech industries. Primarily, we supply to fiber optic manufacturers and high-precision optics companies that require top-quality base materials. These raw materials are used in the fabrication of specialty optical fibers (e.g., for spectroscopy or high-power lasers) and in making optical components like lenses, mirrors, and wafers for semiconductor equipment. For instance, our ultrapure fused silica rods are crucial in the production of polarization-maintaining fibers for aerospace and defense systems. Preforms from WEINERT serve as the starting point for fibers used in telecommunications networks, industrial fiber lasers, and medical devices.
