UVFS Plano-Concave Cylindrical Lenses, Uncoated/AR245-1700nm
Tuniu UV Fused Silica Plano-Concave Cylindrical Lenses are precision non-spherical optical elements, professionally designed for one-dimensional beam shaping and spot size regulation. Featuring a plano-concave cylindrical structure with a negative focal length, these lenses efficiently minimize spherical and chromatic aberration by positioning the concave surface facing the diverging incident beam.
Manufactured from high-quality UV fused silica (UVFS), the material features excellent ultraviolet transmittance and a low thermal expansion coefficient. These UVFS plano-concave cylindrical lenses are widely applied in sanitary equipment production and semiconductor component manufacturing.
Tuniu supplies cylindrical lenses in multiple material options, including N-BK7 and UV fused silica, available in uncoated or anti-reflection (AR) coated versions. Uncoated lenses offer a wide working spectrum and high laser damage threshold. Four standard AR coating bands are available for UVFS lenses: 245–400 nm, 350–700 nm, 650–1100 nm, and 1050–1700 nm. Custom services covering lens size, focal length, material and coating are provided to meet diverse application demands. Please contact our technical support team for personalized requirements.
