UV grade calcium fluoride meniscus lenses are high-purity single-crystal optical lenses specifically engineered for ultraviolet broadband optical systems. Featuring a meniscus structure with one convex surface and one concave surface, the lens delivers effective aberration correction while maintaining excellent deep UV transmittance performance. Manufactured with strict low-defect crystal growth and deep impurity removal technology, this UV specialized CaF₂ material features ultra-low solarization, negligible intrinsic absorption and no UV-induced fluorescence. The lens provides stable optical performance and consistent beam quality under long-term deep ultraviolet irradiation, making it a core optical component for high-precision UV light collimation, focusing and optical path correction.
