UVFS Plano-Convex Round Cylindrical Lenses, Uncoated/AR245-1700nm
Tuniu plano-convex round cylindrical lenses are high-performance one-dimensional beam-shaping optical elements designed to modulate spot size through single-axis light manipulation. Adopting a plano-convex cylindrical configuration with positive focal length, these lenses deliver superior aberration control; arranging the convex surface as the incident side efficiently minimizes spherical and chromatic aberrations.
Fabricated from premium UV fused silica (UVFS), the material features outstanding ultraviolet transmittance and a low thermal expansion coefficient, making these cylindrical lenses well-suited for medical equipment and semiconductor processing applications.
Tuniu supplies cylindrical lenses in multiple material options including N-BK7 and UV fused silica. All variants are offered in uncoated and anti-reflection (AR) coated versions. Uncoated lenses provide broadband spectral coverage and a high laser damage threshold. For UVFS lenses, four standard AR coating spectra are available: 245–400 nm, 350–700 nm, 650–1050 nm and 1050–1700 nm. Custom solutions covering customized dimensions, focal lengths, materials and coatings are available. Please contact our technical team for specialized customization demands.
