UVFS Plano-Concave Round Cylindrical Lensess, Uncoated/AR245-1700nm
Tuniu UV Fused Silica (UVFS) Plano-Concave Round Cylindrical Lenses are professional one-dimensional beam-shaping optical components, specifically designed to adjust and reshape beam spot size along a single axis. Engineered with a plano-concave cylindrical profile and negative focal length, these lenses effectively minimize spherical and chromatic aberrations by positioning the concave surface facing the incoming diverging beam for optimal optical performance.
Manufactured from high-quality UV fused silica, the material delivers exceptional ultraviolet transmittance and a low thermal expansion coefficient. Featuring stable optical performance, these plano-concave cylindrical lenses are well suited for medical equipment and semiconductor manufacturing applications.
Tuniu provides cylindrical lenses in multiple material options, including N-BK7 and UV fused silica. Each material version is available in uncoated or anti-reflection (AR) coated configurations. Uncoated lenses offer a broad operating spectral range and a high laser damage threshold. UVFS lenses come with four standard AR coating options: 245–400 nm, 350–700 nm, 650–1050 nm, and 1050–1700 nm. Custom sizes, focal lengths, materials and specialized coatings are available upon request to fit unique application scenarios.
